Participants

Reaction Steps

To a mixture of 2-(2-ethylbenzoimidazol-1-yl)-9-methyl-6-morpholin-4-yl-8-piperidin-4-ylmethyl-9H-purine hydrochloride (13 mg, 0.02 mmol), sodium L-lactate (5 mg, 0.04 mmol) and HOBt (4 mg, 0.03 mmol) in THF (1 mL) was added NMM (5 μL, 0.05 mmol) and EDCI (8 mg, 0.04 mmol) and the resulting mixture was stirred at r.t. for 1 h. The reaction mixture was partitioned between EtOAc and H2O, the organic layer washed with brine, dried (Na2SO4) and concentrated in vacuo. The resulting residue was purified by column chromatography (Si—PCC, 2M NH3/MeOH:DCM, 0-10%) affording 862 (12 mg, 92%). LCMS (method I): RT 3.18 min, [M+H]+ 533.3. 1H NMR (MeOD, 400 MHz): δ 8.00-7.96 (1 H, m), 7.65-7.61 (1 H, m), 7.28-7.27 (2 H, m), 4.56-4.54 (2 H, m), 4.33 (4 H, brd s), 4.04-4.04 (1 H, m), 3.84 (4 H, t, J=4.75 Hz), 3.79 (3 H, s), 3.17-3.04 (2 H, m), 2.92-2.86 (2 H, m), 2.76-2.64 (1 H, m), 2.28-2.25 (1 H, m), 1.92-1.82 (2 H, m), 1.38 (3 H, t, J=7.51 Hz), 1.36-1.26 (6 H, m)
