Procedure

To a solution of 5-[6-(4-methanesulphonyl-piperazin-1-ylmethyl)-4-morpholin-4-yl-thieno[3,2-d]pyrimidin-2-yl]-thiazol-2-ylamine (12 mg, 0.024 mmol) in THF (1 ml) at RT triethylamine (8 ul, 0.053 mmol, 2 eq) and acetyl chloride (2 ul, 0.026 mmol, 1.1 eq) was added and the reaction allowed to stir at RT overnight. The solution was extracted into ethyl acetate (10 ml) washing with water (2×10 ml), and dried over MgSO4. The crude material was triturated with diethyl ether to give 401 as a yellow solid (7 mg, 54% yield). NMR (CDCl3, 400 MHz), 2.34 (3H, s), 2.69 (4H, t, J=4.8), 2.83 (3H, s), 3.22 (4H, t, J=4.8), 3.89-3.91 (6H, m), 4.03 (4H, t, J=4.8), 7.33 (1H, s), 8.23 (1H, s), 9.44 (1H, br s). MS: (ESI+): MH+=538
