Procedure

1-(2-Chloro-4-morpholin-4-yl-thieno[3,2-d]pyrimidin-6-ylmethyl)-4-(4-chloro-phenyl)-piperidin-4-ol (146 mg, 0.30 mmol) was reacted with 2-amino-pyrimidine-5-boronic acid pinacol ester (94 mg, 0.45 mmol) in General Procedure A. After extraction into 2M HCl, the mixture was washed with EtOAc then made basic and the precipitate collected by filtration. Purification on silica gave 421 as a pale yellow solid (75 mg, 0.14 mmol). NMR (CD3OD, 400 MHz), 9.19 (s, 2H); 7.52 (m, 2H); 7.39 (s, 1H), 7.35 (m, 2H); 4.08 (t, 4H, J=4.1 Hz); 3.97 (s, 2H); 3.89 (t, 4H, J=4.8 Hz); 2.87 (d, 2H); 2.70 (t, 2H, J=11.2 Hz); 2.18 (m, 2H); 1.77 (d, 2H, J=13.2 Hz)_MS: (ESI+): MH+=538.27
