Procedure

2-Chloro-6-(4-methanesulfonyl-piperidin-1-ylmethyl)-4-morpholin-4-yl-thieno[3,2-d]pyrimidine, prepared following Example 46, was reacted with 2-aminopyrimidine-5-boronic acid pinacol ester via General Procedure A. Purification on silica yielded 130. NMR (DMSO): 1.61-1.68 (2H, m), 2.01-2.08 (2H, m), 2.12-2.18 (2H, m), 2.94 (3H, s, Me), 3.02-3.11 (3H, m), 3.76-3.80 (4H, m, CH2), 3.89 (2H, s, CH2), 3.96-3.99 (4H, m, CH2), 7.02 (2H, s, NH2), 7.32 (1H, s, Ar) and 9.10 (2H, s, Ar). MS: (ESI+): MH+=490.34
