Reaction Conditions

Reaction Steps

Chloroacetic acid chloride (0.93 ml; II.42 mmol) is dropped slowly into a stirred solution of 5-t-Butyl-3-amino isoxazole (1.5 g; 7.67 mmol) in pyridine (1.09 ml; 13.49 mmol) and dichloromethane (20 ml), cooled to 0° C. Stirring is continued for 2 h at room temperature. The reaction mixture is diluted with dichloromethane, washed twice with 1N aqueous hydrochloric acid, twice with an aqueous solution of NaHCO3 and with water. The reaction mixture is then dried over Na2SO4, filtered and evaporated to yield 2.2 g (98%) brownish solid of 10.
