Reaction Steps

(2-Chloro-4-morpholin-4-yl-thieno[3,2-d]pyrimidin-6-ylmethyl)methylamine was reacted with 1-ethyl-4-piperidone using standard reductive amination conditions. The resulting crude solid was triturated with a small amount of diethyl ether and methanol to give (2-chloro-4-morpholin-4-yl-thieno[3,2-d]pyrimidin-6-ylmethyl)-(1-ethyl-piperidin-4-yl)-methyl-amine as a 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 triturated with diethylether and methanol to give 347 as a solid (75% yield). NMR (CDCl3, 400 MHz), 1.10 (3H, t, J=7.2), 1.56-1.73 (2H, m), 1.84-1.95 (4H, m), 2.38 (3H, s), 2.42 (2H, q, J=7.0), 2.51-2.58 (1H, m), 3.06 (2H, d, J=11.8), 3.88-3.91 (4H, m), 3.93 (2H, s), 4.03-4.06 (4H, m), 5.21 (2H, br s), 7.27 (1H, s), 9.30 (2H, s).
