実験手順: (2-Chloro-4-morpholin-4-yl-thieno[3,2-d]pyrimidin-6-ylmethyl)methylamine was reacted with 1-(2-methoxy-ethyl)piperidin-4-one using standard reductive amination conditions. The resulting crude solid was triturated with diethyl ether and methanol to give (2-chloro-4-morpholin-4-yl-thieno[3,2-d]pyrimidin-6-ylmethyl)-[1-(2-methoxy-ethyl)-piperidin-4-yl]-methyl-amine as an off white solid (32% 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 343 as a solid (43% yield).
