(2-Chloro-4-morpholin-4-yl-thieno[3,2-d]pyrimidin-6-ylmethyl)-methylamine was reacted with 1-propyl-piperidin-4-one using standard reductive amination conditions. The resulting crude solid was triturated was with diethyl ether and methanol to give (2-chloro-4-morpholin-4-yl-thieno[3,2-d]pyrimidin-6-ylmethyl)-methyl-(1-propyl-piperidin-4-yl)amine as a solid (30% 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 diethylether and methanol to give 344 as a solid (77% yield).
