Procedure

2-Chloro-4-morpholin-4-yl-thieno[3,2-d]pyrimidine-6-carboxaldehyde 10 was reacted with dimethyl-piperidin-4-yl-amine using standard reductive amination conditions. The resulting crude solid was triturated with diethyl ether to give [1-(2-chloro-4-morpholin-4-yl-thieno[3,2-d]pyrimidin-6-ylmethyl)-piperidin-4-yl]-dimethyl-amine as an off white solid (45% yield), which 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 mass directed chromatography (20% yield) to give 337. NMR (CDCl3, 400 MHz), 1.60-1.65 (2H, m), 1.83-1.86 (2H, d, J 12.2), 2.11-2.17 (3H, m), 2.32 (6H, s), 3.04 (2H, d, J 11.4), 3.83 (2H, s), 3.88-3.91 (4H, m), 4.03-4.06 (4H, m), 5.24 (2H, br s), 7.27 (1H, br s), 7.27 (1H, s), 9.30 (2H, s).
