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 2,4-dimethoxy-5-(4,4,5,5-tetramethyl-[1,3,2]dioxaborolan-2-yl)-pyrimidine in General Procedure A. Purification on silica yielded 225. NMR (400 MHz CDCl3): 2.68 (4H, m, CH2), 2.81 (3H, s, CH3), 3.30 (4H, m, CH2), 3.85-3.88 (6H, m, CH2), 4.00-4.03 (4H, m, CH2), 4.06 (3H, s, CH3), 4.09 (3H, s, CH3), 7.33 (1H, s, ar), 8.93 (1H, s, ar).
