Participants

Reaction Steps

A mixture of 2-(2,2-dimethylpiperazin-1-ylmethyl)-5-(2-ethylbenzoimidazol-1-yl)-7-morpholin-4-ylthiazolo[5,4-d]pyrimidine (200 mg, 0.41 mmol), L-lactic acid (34 μL, 85% solution in H2O), HATU (170 mg, 0.45 mmol) and DIPEA (80 μL, 0.46 mmol) in DCM (4 mL) was allowed to stir at r.t. for 3 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:EtOAc, 0-2%) then (C18, MeOH:H2O, 10-20%). The resulting residue was loaded onto an Isolute® SCX-2 cartridge which was washed with MeOH and the product eluted with 2M NH3/MeOH affording 829 (41 mg, 18%). LCMS (method I): RT 3.79 min, [M+H]+ 565.3. 1H NMR (CDCl3, 400 MHz): δ 8.03-7.98 (1 H, m), 7.76-7.75 (1 H, m), 7.32-7.22 (2 H,m), 4.41-4.38 (5 H, m), 4.08-4.01 (1 H, m), 3.89-3.88 (5 H, m), 3.79-3.77 (1 H, m), 3.59-3.44 (2 H, m), 3.34 (2 H, q, J=7.47 Hz), 3.27-3.25 (1 H, m), 2.75 (2 H, s), 1.44 (3 H, t, J=7.47 Hz), 1.37-1.35 (3 H, m), 1.27-1.11 (6 H, m)
