Procedure

2-Chloro-4-morpholin-4-yl-thieno[3,2-d]pyrimidine-6-carboxaldehyde 10 was reacted with 3-(dimethylamino)pyrrolidine using standard reductive amination conditions. The resulting crude oil was triturated with diethyl ether and methanol to give [1-(2-chloro-4-morpholin-4-yl-thieno[3,2-d]pyrimidin-6-ylmethyl)-pyrrolidin-3-yl]dimethyl-amine as a solid (61% 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 triturated with diethyl ether and methanol to give 341 as an off white solid (86% yield). NMR (CDCl3, 400 MHz), 1.76-1.82 (1H, m), 2.20-2.10 (1H, m), 2.23 (6H, s), 2.48 (2H, dd, J=7.4 and 8.5), 2.66-2.17 (2H, m), 2.81-2.95 (3H, m), 3.88-3.90 (4H, m), 3.90-3.99 (2H, m), 4.03-4.06 (4H, m), 5.23 (2H, br s), 7.28 (1H, s), 9.30 (2H, s).
