Synthetic Route of 23787-80-6,Some common heterocyclic compound, 23787-80-6, name is 1-(3-Methylpyrazin-2-yl)ethanone, molecular formula is C7H8N2O, traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route.

General procedure: Almac CRED (200 mg),NADP or NAD (10 mg), GDH (20 mg) and glucose (1.5 equiv) weremeasured into a 100 mL round bottomed flask then dissolved in0.1 M potassium phosphate buffer (pH 7, ca. 50 mL) and stirredat 30 C. Next, a solution of ketone (900-1700 mg) in DMSO(2.5-5 mL, depending on solubility) was added to the reactionand this was allowed to stir overnight under pH-stat control (pH7.0, adjusted with 1 M NaOH solution). The following day, reactionprogress was checked by 1H NMR. If not complete, additional CRED(100-200 mg), NADP or NAD (10 mg) and GDH (10 mg) wereadded and stirring was continued. This was repeated until the reactionreached completion or had stalled and would not go any further.

These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 1-(3-Methylpyrazin-2-yl)ethanone, its application will become more common.

Application of 23787-80-6, These common heterocyclic compound, 23787-80-6, name is 1-(3-Methylpyrazin-2-yl)ethanone, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route.

General procedure: General procedure: 8-Hydrazinocaffeine (3) (112 mg;0.5 mmol) and carbonyl compound (1 mmol; 2 eq.) were mixedin ethanol (20 mL, containing 0.2 mL of acetic acid) and heated at 75 omicronC for 3 days. After cooling down, reaction mixture was evaporatedto dryness and solid residue was suspended in diethyl ether(50 mL), filtered off, washed with additional portion of diethylether (3 25 mL) and dried in vacuo at 50 C to obtain the hydrazone.

Statistics shows that 1-(3-Methylpyrazin-2-yl)ethanone is playing an increasingly important role. we look forward to future research findings about 23787-80-6.

23787-80-6, name is 1-(3-Methylpyrazin-2-yl)ethanone, belongs to Pyrazines compound, is considered to be a conventional heterocyclic compound, which is widely used in drug synthesis. The chemical synthesis route is as follows. Quality Control of 1-(3-Methylpyrazin-2-yl)ethanone

To a chloroform (7.5 mL) solution of 1-(3-methylpyrazin-2-yl)ethanone (0.50 g), under ice cooling in a nitrogen atmosphere, 2,6-lutidine (0.75 mL) and trimethylsilyl trifluoromethanesulfonate (0.80 mL) were added, and the resultant was stirred for 30 minutes. Then, N-bromosuccinimide (0.73 g) was added thereto, and the resultant was stirred for 1 hour under ice cooling. Water was added to the reaction solution, and the resultant was stirred for 10 minutes, followed by extraction with chloroform. An organic layer was separated using a phase separator, and the solvent was distilled off under reduced pressure. The obtained residue was purified by silica gel column chromatography (OH-type silica gel; hexane/ethyl acetate-gradient elution=95/5?85/15) to obtain the title compound (0.58 g) as a brown solid.1H NMR (600 MHz, CHLOROFORM-d) deltappm 2.87 (3H, s), 4.79 (2H, s), 8.50 (1H, d, J=2.1 Hz), 8.65 (1H, d, J=2.1 Hz)

The synthetic route of 23787-80-6 has been constantly updated, and we look forward to future research findings.
