Reaction Steps

(2-Chloro-4-morpholin-4-yl-thieno[3,2-d]pyrimidin-6-ylmethyl)methylamine was reacted with 1-cyclopropyltetrahydro-4(1H)-pyridinone 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-cyclopropyl-piperidin-4-yl)methyl-amine as a solid (57% 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 purified by mass directed chromatography (18% yield) to give 339. NMR (CDCl3, 400 MHz), 0.39-0.47 (4H, m), 1.58-1.66 (3H, m), 1.83 (2H, d, J=12.1), 2.19 (2H, t, J=9.9), 2.36 (3H, s), 2.54-2.58 (1H, m), 3.13 (2H, d, J=11.5), 3.88-3.92 (6H, m), 4.03-4.06 (4H, m), 5.22 (2H, br s), 7.27 (1H, s), 9.30 (2H, s).
