2-Chloro-4-morpholin-4-yl-thieno[2,3-d]pyrimidine-6-carboxaldehyde was reacted with (2-methoxy-ethyl)-methyl-piperidin-4-yl-amine using standard reductive amination conditions to give [1-(2-chloro-4-morpholin-4-yl-thieno[2,3-d]pyrimidin-6-ylmethyl)-piperidin-4-yl]-(2-methoxy-ethyl)-methyl amine as a solid, which was reacted with methyl-[5-(4,4,5,5-tetramethyl-[1,3,2]dioxaborolan-2-yl)-pyridin-2-yl]-carbamic acid tert-butyl ester according to General Procedure A. The resulting solid was triturated with diethyl ether to give 367 as an off white solid (35% yield).
