HCID 66934304Tert-butyl 4-((2-(2-aminopyrimidin-5-yl)-4-morpholinothieno[3,2-d]pyrimidin-6-yl)methyl)piperazine-1-carboxylateYield 88.6%

Procedure

Tert-butyl 4-((2-chloro-4-morpholinothieno[3,2-d]pyrimidin-6-yl)methyl)piperazine-1-carboxylate (2.4 gm) was reacted with 1.64 gm 5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)pyrimidin-2-amine via General Procedure A to yield 2.4 g tert-butyl 4-((2-(2-aminopyrimidin-5-yl)-4-morpholinothieno[3,2-d]pyrimidin-6-yl)methyl)piperazine-1-carboxylate. 150 mg of this crude intermediate was subjected to procedure D and subsequently reacted with 84 mg D-lactic Acid via General Procedure B to give 102.5 mg of 400 after reverse phase HPLC purification. MS (Q1) 485.2 (M)+.
