Procedure

To a mixture of 8-azetidin-3-ylmethyl-2-(2-ethylbenzoimidazol-1-yl)-9-methyl-6-morpholin-4-yl-9H-purine (57 mg, 0.13 mmol), D-lactic acid (14 mg, 0.16 mmol) and DIPEA (27 μL, 0.16 mmol) in DCM (2 mL) and DMF (1.5 mL) was added HATU (60 mg, 0.16 mmol). The resulting yellow mixture was stirred for 2 h at r.t. then partitioned between DCM and H2O. The combined organic phases were dried (Na2SO4) and concentrated in vacuo. The resulting residue was purified by column chromatography (Si—PCC, MeOH:EtOAc, 0-10%) followed by Isolute® SCX-2 cartridge which was washed with MeOH/DCM and the product eluted with 2M NH3/MeOH affording 679 as a cream foam (23 mg, 35%). LCMS: RT 2.92 min, [M+H]+ 505.2. 1H NMR (CDCl3, 400 MHz): δ 8.00-7.98 (1 H, m), 7.81-7.70 (1 H, m), 7.26 (2 H, s), 4.49-4.20 (7 H, m), 3.91 (1 H, dd, J=10.38, 5.67 Hz), 3.86 (5 H, t, J=4.71 Hz), 3.76-3.75 (3 H, m), 3.36-3.35 (4 H, m), 3.18-3.15 (2 H, m), 1.44 (3 H, t, J=7.46 Hz), 1.34 (3 H, dd, J=6.68, 4.79 Hz)
