实验步骤: To a solution of 2-chloro-4-trifluoromethyl-pyrimidin-5-carbonyl chloride (1.0 g, ex Maybridge) in dichloromethane (7 ml) at −2° was added a dropwise a solution of cyclopentanemethanamine hydrochloride (0.55 g) and triethylamine (1.4 ml) in dichloromethane (13 ml) and the solution stirred at 0° for 1 hour. Dichloromethane was removed under reduced pressure and ethyl acetate (20 ml) added.
