反应详情

Stir a solution of 2N dimethylamine (9.00 mL, 18.08 mmol) in tetrahydrofuran, N,N-diisopropylethylamine (2.80 g, 3.80 mL, 21.69 mmol) while adding a solution of 2-bromomethyl-4-tert-butyl-6-chloro-pyridine (1.90 g, 7.23 mmol) in tetrahydrofuran (20 mL). Stir for 2.5 hours at ambient temperature, dilute the reaction with aqueous sodium bicarbonate (80 mL) and extract the aqueous layer with ethyl acetate (3×75 mL). Pool, desiccate, filter and concentrate the organics to yield the title compound (99%) (1.64 g, 7.23 mmol). MS(ES), m/z 227 (M+1).
