Procedure

4-(2-Chloro-4-morpholin-4-yl-thieno[3,2-d]pyrimidin-6-ylmethyl)-piperazine-1-carboxylic acid (2-methoxy-ethyl)-methyl-amide (Example 27) was reacted with 5-(4,4,5,5-tetramethyl-[1,3,2]dioxaborolan-2-yl)-pyrimidin-2-ylamine via General Procedure A. Purification on silica yielded 155. NMR (CDCl3): 2.57-2.60 (m, 4H, 2×CH2), 2.92 (s, 3H, CH3), 3.31-3.33 (m, 4H, 2×CH2), 3.36 (s, 3H, CH3), 3.38-3.41 (m, 4H, 2×CH2), 3.55-3.57 (m, 4H, 2×CH2), 3.86 (s, 2H, CH2), 3.89-3.92 (m, 4H, 2×CH2), 4.04-4.06 (m, 4H, 2×CH2), 5.28 (sbr, 2H, NH2), 7.29 (s, H, ArH), 7.33 (s, H, ArH), 9.29 (s, 2H, 2×ArH). MS: (ESI+): MH+ 528.44
