To a solution of 4-[2-(3-chloro-phenyl)-2(S)-hydroxy-ethylamino]-3-(6-methyl-2-piperazin-1-yl-9H-purin-8-yl)-1H-pyridin-2-one (20 mg, 0.042 mmol) in a mixture of THF:DMF (1.5 mL:0.5 mL) was added glacial acetic acid (2.3 μl, 0.042 mmol) and 2-methylbutyraldehyde (12 μl, 0.117 mmol). The reaction mixture was stirred at 23° C. for 3 hours followed by the addition of NaBH(OAc) 3 (24.9 mg, 0.117 mmol) to the reaction mixture and stirred for an additional 18 hours. MeOH (0.5 mL) was added and the solution was passed through a SCX cartridge (1 g, 0.79 meq/g, varian). The cartridge was eluted with MeOH (16 mL) and with 2N ammonia in MeOH (16 mL). The ammonia solution was evaporated in vacuo and the solid obtained was purified using a Shimadzu automated preparative HPLC System with the method described below. The solution was evaporated on a Savant Speedvac system to give the title compound as a light yellow solid. (14.2 mg, 62%).
