Participants

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.
