Related Products of 33332-30-8,Some common heterocyclic compound, 33332-30-8, name is 2-Chloro-6-methoxypyrazine, molecular formula is C5H5ClN2O, 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.
Example 137 A mixture of 2-chloro-6-methoxypyrazine (500 mg, 3.46 mmol, 1.0 eq), bis(pinacolato)diboron (1.05 g, 4.13 mmol, 1.2 eq), Pd2(dba)3 (95 mg, 0.1 mmol, 0.029 eq), P(Cy)3 (120 mg, 0.43 mmol, 0.13 eq), and potassium acetate (600 mg, 6.11 mmol, 1.77 eq) in 1,2-dimethoxyethane (10 mL) was irradiated under argon at 150 C. in a microwave oven for 3 h. The mixture was allowed to cool to RT, quenched with water and extracted with ethyl acetate. The combined organic layers were washed with brine, dried over Na2SO4 and filtered. The filtrate was concentrated in vacuo to afford the pinacol ester (600 mg).
The synthetic route of 33332-30-8 has been constantly updated, and we look forward to future research findings.
