Versuchsvorschrift

To a solution of (2-chloro-9-methyl-6-morpholin-4-yl-9H-purin-8-yl)acetaldehyde (150 mg, 0.51 mmol) in DCE (10 mL) was added 2-piperidin-4-ylpropan-2-ol (110 mg, 0.77 mmol), trimethyl orthoformate (0.55 mL, 5.02 mmol) and acetic acid (0.03 mL, 0.52 mmol). The reaction mixture was stirred at room temperature for 5 h, sodium triacetoxyborohydride (154 mg, 0.73 mmol) was added and the resulting mixture stirred for a further 2 h. The reaction mixture was loaded onto an Isolute® SCX-2 cartridge, the cartridge was washed with MeOH then the desired product eluted with 2 M NH3 in MeOH. The resulting residue was purified by column chromatography (Si—PCC, 0-10% MeOH in DCM) to give the title compound as an off white solid (109 mg, 51%). LCMS (Method H): RT=2.54 min, [M+H]+ 423.5
