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.
