Procedure

4-((2-Chloro-4-morpholinothieno[2,3-d]pyrimidin-6-yl)methyl)-N,N-dimethylpiperazine-1-carboxamide was reacted with pyrimidine-5-boronic acid in General Procedure A. Purification on silica yielded 268. NMR (CDCl3): 2.55-2.57 (m, 4H, 2×CH2), 2.84 (s, 6H, 2×CH3), 3.31-3.33 (m, 4H, 2×CH2), 3.80 (s, 2H, CH2), 3.90-3.92 (m, 4H, 2×CH2), 3.99-4.02 (m, 4H, 2×CH2), 7.19 (s, H, ArH), 9.28 (s, H, ArH), 9.69 (s, 2H, 2×ArH). MS: (ESI+): MH+=469.24
