Reaction Steps

A solution of pyridazin-4-ylamine (1.0 g) in dry dichloromethane (10 mL) under nitrogen was cooled to 0° C. in an ice bath. Triethylamine (1.6 mL) was added, followed by slow addition of chloroacetyl chloride (0.92 mL). On completion of the addition the ice bath was removed and the reaction mixture was allowed to reach room temperature and stirred for 2 hours. The reaction mixture was diluted with water (25 mL) and dichloromethane (30 mL) A solid was filtered off and washed with pentane, water and more pentane to give the sub-titled compound (0.87 g, 48%) as a brown solid.
