Procedure

A mixture of 2-(2-cyclopropylbenzoimidazol-1-yl)-9-methyl-6-morpholin-4-yl-9H-purine-8-carboxylic acid (200 mg, 0.48 mmol), 2-piperidin-4-ylpropan-2-ol (78 mg, 0.55 mmol), HATU (205 mg, 0.54 mmol) and DIPEA (96 μL, 0.55 mmol) in DCM (5 mL) was allowed to stir at r.t. for 19 h. The reaction mixture was loaded onto an Isolute® SCX-2 cartridge which was washed with MeOH and the product eluted with 2M NH3/MeOH. The resulting residue was purified by column chromatography (Si—PCC, MeOH:DCM, 0-3%) then (Si—PCC, MeOH:EtOAc, 0-5%) affording 798 as a white solid (138 mg, 53%). LCMS (method G): RT 7.50 min, [M+H]+ 545.4. 1H NMR (CDCl3, 400 MHz): δ 7.97-7.96 (1 H, m), 7.68-7.67 (1 H, m), 7.28-7.20 (2 H, s), 4.91-4.82 (1 H, m), 4.68-4.65 (1 H, m), 4.40 (4 H, brd s), 3.97 (3 H, s), 3.86 (4 H, t, J=4.70 Hz), 3.18-3.10 (1 H, m), 2.84-2.83 (2 H, m), 1.94-1.92 (2 H, m), 1.64-1.62 (1 H, m), 1.44-1.43 (2 H, m), 1.35-1.34 (2 H, m), 1.24-1.22 (7 H, m), 1.06-1.05 (2 H, m)
