Procedure

A suspension of (2-chloro-4-morpholin-4-ylthieno[3,2-d]pyrimidin-6-ylmethyl)-(1-isopropyl-piperidin-4-yl)-methyl-amine (61 mg, 0.144 mmol), 5-(4,4,5,5-tetramethyl-[1,3,2]dioxaborolan-2-yl)-pyrimidin-2-ylamine (37 mg, 0.17 mmol), 1M Na2CO3 (0.5 ml, 0.5 mmol) and Pd(PPh3)2Cl2 (10 mg, 0.014 mmol) in acetonitrile was heated in a microwave at 140° C. for 25 mins. The reaction was then acidified with 2N HCl (aq) extracted with ethyl acetate, the water layer separated and made basic with K2CO3 (sat. aq) resulting in a precipitate, purified on alumina using 5% methanol in dichloromethane as the eluent to give 419 (11 mg, 16%). NMR (CDCl3, 400 MHz), 1.05 (6H, d, J=6.8), 1.60-1.69 (2H, m), 1.72-1.76 (2H, m), 2.08-2.15 (2H, m), 2.37 (3H, s), 2.48-2.54 (1H, m), 2.71-2.76 (1H, m), 2.95-3.00 (2H, m), 3.89 (4H, t, J=4.4), 3.99 (2H, s), 4.05 (4H, t, J=4.8), 5.2 (2H, s), 7.27 (1H, s), 9.30 (2H, s). MS: (ESI+): MH+=483.
