Procedure
2-Chloro-6-(4-methanesulfonyl-piperazin-1-ylmethyl)-4-morpholin-4-yl-thieno[3,2-d]pyrimidine, prepared via General Procedure B-3, was reacted with 2-amino-pyridine-5-boronic acid pinacol ester in General Procedure A. Purification on silica and ether trituration gave 240. NMR (CDCl3): 2.67-2.71 (4H, m), 2.81 (3H, s), 3.29-3.33 (4H, m), 3.89 (2H, s), 3.89-3.93 (4H, m), 4.08-4.12 (4H, m), 4.60-4.65 (2H, br. s), 6.57 (1H, d, J=8.6), 7.40 (1H, s), 8.45 (1H, dd, J=8.6, 2.2), 9.17 (1H, d, J=2.2). MS (ESI+): MH+490.18 (100%)
