Participants

Reaction Steps

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 basified and the precipitate collected by filtration. Purification on silica gave 317 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
