Reaction Steps

A mixture of 9.52 g of 4-chloro-2-(4-chloro-2,5-difluorophenyl)thieno[3,2-d]pyrimidine, 3.13 g of hexamethyleneimine, 10.50 ml of diisopropyl ethylamine and 190 ml of acetonitrile was stirred for 5 hours at 70° C. 600 ml of water was added to the reaction mixture and the precipitate was filtered, washed with water and dried at 50° C. under reduced pressure. The obtained solid was dissolved in 40 ml of THF. The solution was added to 15 ml of 4M HCl-EtOAc solution and concentrated under reduced pressure to give a solid. Through recrystallization of this solid from EtOH-ether, 10.97 g of 4-azepane-1-yl-2-(4-chloro-2,5-difluorophenyl)thieno[3,2-d]pyrimidine hydrochloride was obtained.
