Tert-butyl 4-((2-chloro-7-methyl-4-morpholinothieno[3,2-d]pyrimidin-6-yl)methyl)piperazine-1-carboxylate (1.49 gm) was reacted with 985 mg 5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)pyrimidin-2-amine via General Procedure A to yield 1.62 g tert-butyl 4-((2-(2-aminopyrimidin-5-yl)-7-methyl-4-morpholinothieno[3,2-d]pyrimidin-6-yl)methyl)piperazine-1-carboxylate. 150 mg of this crude intermediate was subjected to General Procedure D and subsequently reacted with 84 mg D-lactic Acid via General Procedure B to give 106.3 mg of 399 after reverse phase HPLC purification.
