Reaction Steps

75 μl of methanesulfonyl chloride was added to a mixture comprising 100 mg of 4-(3-amino-4-chlorobenzyl)amino-6-chloroquinazoline and 3 ml of pyridine. The obtained mixture was stirred at room temperature for 1.5 hours. 20 ml of water was added in portions to the reaction mixture to precipitate crystals. The crystals were recovered by filtration, washed with water and dried to give 109 mg of the title compound.
