Procedure

A mixture of 5-chloro-7-morpholin-4-ylthiazolo[5,4-d]pyrimidine-2-carboxylic acid (200 mg, 0.67 mmol), 2-piperidin-4-ylpropan-2-ol (105 mg, 0.73 mmol), HATU (278 mg, 0.73 mmol) and DIPEA (130 μL, 0.75 mmol) in DCM (7 mL) was allowed to stir at r.t. for 18 h. The reaction mixture was concentrated in vacuo and the resulting residue purified by column chromatography (Si—PCC, MeOH:DCM, 0-2%) affording the title compound as a white solid. 1H NMR (CDCl3, 400 MHz): δ 5.15 (1 H, d, J=13.36 Hz), 4.79 (1 H, d, J=13.25 Hz), 4.35 (4 H, brd s), 3.85 (4 H, t, J=4.75 Hz), 3.16-3.13 (1 H, m), 1.92 (2 H, t, J=15.39 Hz), 1.75-1.60 (1 H, m), 1.49-1.38 (4 H, m), 1.22 (6 H, d, J=6.97 Hz).
