Reaction Steps

A mixture of 260 mg of 1-[2-(4-chloro-2,5-difluorophenyl)thieno[3,2-d]pyrimidine-4-yl]azepane-4-carbonitrile and 35% HCl aq was stirred for 3 hours at 80° C. After the reaction mixture was concentrated and dried under reduced pressure, the obtained residue was purified by silica gel column chromatography (chloroform-MeOH) to give a solid. THF and 0.2 ml of 4M HCl-EtOAc solution were added to the obtained solid. After the solvent was removed under reduced pressure, the residue washed with EtOAc to give 250 mg of 1-[2-(4-chloro-2,5-difluorophenyl)thieno[3,2-d]pyrimidine-4-yl]azepane-4-carboxylic acid hydrochloride.
