HCID 574939772-Chloro-4-morpholin-4-yl-6-(4-morpholin-4-yl-piperidin-1-ylmethyl)-thieno[3,2-d]pyrimidine

Procedure

2-Chloro-4-morpholin-4-yl-thieno[3,2-d]pyrimidine-6-carboxaldehyde 10 was reacted with 4-piperidin-4-yl-morpholine using standard reductive amination conditions. The resulting crude solid was triturated with methanol to give 2-chloro-4-morpholin-4-yl-6-(4-morpholin-4-yl-piperidin-1-ylmethyl)-thieno[3,2-d]pyrimidine as an off white solid (50% 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 to give 336 as an off white solid (21% yield). NMR (CDCl3, 400 MHz), 1.60-1.67 (2H, m), 1.86 (2H, d, J=12.2), 2.14 (2H, t, J=10.6), 2.17-2.23 (1H, m), 2.57-2.59 (4H, m), 3.05 (2H, d, J=11.7), 3.73-3.75 (4H, m), 3.83 (2H, s), 3.88-3.91 (4H, m), 4.03-4.06 (4H, m), 5.21 (2H, br s), 7.27 (1H, s), 9.30 (2H, s). MS: (ESI+): MH+=497
