Procedure: (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).

Procedure: To a solution of 4-piperidone monohydrate hydrochloride salt (2.2 g, 14.32 mmol, 1 eq) in acetonitrile, 2-bromoethyl methyl ether (5.9 ml, 28.6 mmol, 2 eq), and K2CO3 (2 eq) was added and heated at reflux overnight. Reaction extracted into dichloromethane (50 ml), washed with water (2×50 ml), dried (MgSO4), and evaporated in vacuo to give 1-(2-methoxy-ethyl)piperidin-4-one as a yellow oil. heated at reflux overnight Reaction extracted into dichloromethane (50 ml) washed with water (2×50 ml) dried (MgSO4) evaporated in vacuo

Procedure: 4-Piperidone hydrochloride monohydrate (1.00 g, 6.50 mmol), 2-bromoethyl methyl ether (1.00 g, 7.20 mmol) and K2CO3 (1.80 g, 13.0 mmol) were dissolved in MeCN (20 mL) and the reaction mixture was stirred at 75° C. for 6 h. The reaction mixture was filtered and the solvents removed in vacuo. The residue was dissolved in DCM (30 mL), stirred with isocyanate resin for 2 h, dried (MgSO4) and concentrated in vacuo to give the crude title compound (180 mg, 18%) as a colourless gum.
