Procedure
To 2-(1H-indazol-4-yl)-6-(4-methanesulfonyl-piperazin-1-ylmethyl)-4-morpholin-4-yl-thieno[3,2-d]pyrimidine (2.00 g, 3.89 mmol) in dichloromethane (50 ml) and methanol (20 ml) was added methanesulfonic acid (2 equiv., 505 ul). The reaction mixture was stirred for 3 hours at room temperature during which time a white precipitate gradually crashed out. Volatiles were removed in vacuo, the residue was triturated with diethyl ether, the solvent decanted and the solid dried under vacuum to give the title compound (2.70g).
