HCID 582339732-(2,4-dimethoxypyrimidin-5-yl)-4-morpholino-6-((4-N-cyclopropylsulfonylpiperazin-1-yl)methyl)thieno[3,2-d]pyrimidine

Procedure

2-Chloro-6-(4-cyclopropanesulfonyl-piperazin-1-ylmethyl)-4-morpholin-4-yl-thieno[3,2-d]pyrimidine (Example 39) was reacted with 2,4-dimethoxy-5-(4,4,5,5-tetramethyl-[1,3,2]dioxaborolan-2-yl)-pyrimidine via General Procedure A. Purification on silica yielded the desired compound. NMR (400 MHz, CDCl3): 1.01-1.04 (2H, m, CH2), 1.20-1.25 (2H, m, CH2), 2.30 (1H, m, CH), 2.67-2.70 (4H, m, CH2), 3.39-3.41 (4H, m, CH2), 2.87-3.88 (4H, m, CH2), 3.90 (2H, s, CH2), 4.03-4.05 (4H, m, CH2), 4.08 (3H, s, CH3), 4.11 (3H, s, CH3), 7.36 (1H, s, ar), 8.95 (1H, s, ar).
