Procedure

A mixture of 2-(2-ethylbenzoimidazol-1-yl)-8-(3-methoxypiperidin-3-yl)-9-methyl-6-morpholin-4-yl-9H-purine dihydrochloride (150 mg, 0.27 mmol) and DIPEA (190 μL, 1.09 mmol) in THF (3 mL) was stirred for 5 min before the addition of methanesulfonyl chloride (21 μL, 0.27 mmol). The resulting mixture was stirred at r.t. for 4 h then partitioned between H2O and DCM. The organic phase was washed with brine, then dried (Na2SO4) and concentrated in vacuo. The resulting residue was purified by column chromatography (Si-PCC, EtOAc:TBME, 0-100%) affording 766 (39 mg, 26%). LCMS (method I): RT 3.74 min, [M+H]+ 555.2. 1H NMR (DMSO, 400 MHz): δ 8.05-8.04 (1 H, m), 7.64-7.63 (1 H, m), 7.28-7.24 (2 H, m), 4.27 (4 H, brd s), 3.97 (1 H, d, J=13.24 Hz), 3.92 (3 H, s), 3.79 (4 H, t, J=4.61 Hz), 3.50-3.47 (2 H, m), 3.28-3.26 (2 H, m), 3.08 (3 H, s), 3.05-2.95 (4 H, m), 2.35-2.25 (1 H, m), 1.98-1.95 (2 H, m), 1.76-1.72 (1 H, m), 1.35 (3 H, t, J=7.43 Hz)
