1.3 g methyl 3-{1-[5-oxo-4-(tetrahydropyran-4-ylamino)-6,7-dihydro-5H-5λ4-thieno[3,2-d]pyrimidin-2-yl]-piperidin-4-yl}-benzoate are placed in 24.6 ml of methanol, then 9.2 ml of a 1 N NaOH solution are added. The reaction mixture is stirred at ambient temperature until there is no further reaction, then combined with a 1 N HCl solution. The methanol is spun off and the precipitated solid is suction filtered. The product is purified by preparative HPLC (method B). 760 mg product are obtained as a solid.
