Procedure

A mixture of 2-(2-ethylbenzoimidazol-1-yl)-8-(3-methoxyazetidin-3-yl)-9-methyl-6-morpholin-4-yl-9H-purine (100 mg, 0.22 mmol), tetrahydropyran-4-one (27 mg, 0.27 mmol) and AcOH (50 μL) in DCE (2 mL) was allowed to stir at r.t. for 20 min before the addition of sodium triacetoxyborohydride (104 mg, 0.49 mmol). The resulting mixture was allowed to stir for 18 h then partitioned between DCM and H2O. The organic phase was dried (phase separator) and concentrated in vacuo. The resulting residue was purified by column chromatography (Si-PCC, MeOH:EtOAc, 0-20%) then triturated with MeCN and H2O and the resulting solid dried in vacuo affording 827 (92 mg, 82%). LCMS (method I): RT 2.65 min, [M+H]+ 555.3. 1H NMR (DMSO, 400 MHz): δ 8.04-8.04 (1 H, m), 7.65-7.62 (1 H, m), 7.25-7.24 (2 H, m), 4.40-4.10 (4 H, brd s), 3.91 (2 H, d, J=8.05 Hz), 3.80-3.79 (6 H, m), 3.71 (3 H, s), 3.41 (2 H, d, J=8.07 Hz), 3.28-3.26 (4 H, m), 3.02 (3 H, s), 2.37-2.28 (1 H, m), 1.67-1.63 (2 H, m), 1.34 (3 H, t, J=7.43 Hz), 1.23-1.10 (2 H, m)
