Reaction Steps

(2-Chloro-4-morpholin-4-yl-thieno[3,2-d]pyrimidin-6-ylmethyl)-methyl-(1-methyl-1H-imidazol-4-ylmethyl)-amine was reacted with 5-(4,4,5,5-tetramethyl-[1,3,2]dioxaborolan-2-yl)-pyrimidin-2-ylamine according to General Procedure A. The resulting solid was purified by flash column chromatography using 10% methanol/ethyl acetate as the eluent to give 295 as a solid (49% yield). NMR (DMSO, 400 MHz), 2.19 (3H, s), 3.62 (2H, s), 3.68 (3H, s), 3.75-3.78 (4H, m), 3.85 (2H, s), 3.93-3.97 (4H, m), 6.85 (1H, s), 7.04 (2H, s), 7.36 (1H, s), 7.58 (1H, s), 9.11 (2H, s).
