Hydrochloric Acid → N-{4-[(3-Amino-1,2-benzisoxazol-4-yl)oxy]-3-fluorophenyl}-N-(2-amino-6-chloro-4-pyrimidinyl)amine

Participants

Reaction Steps

100 mg (0.39 mmol) of 4-(4-amino-2-fluorophenoxy)-1,2-benzisoxazole-3-amine (from example VII) and 63.3 mg (0.39 mmol) of 2-amino-4,6-dichloropyrimidine are suspended in 3 ml of water, and 0.04 ml of concentrated hydrochloric acid is added. The reaction mixture is heated at reflux overnight, resulting in the formation of a colorless precipitate. This is filtered off, washed repeatedly with water and dried under high vacuum.
