Reaction Steps
A solution of (R/S,S/R)—N-(2-chloro-5-fluoropyrimidin-4-yl)-octahydro-5,5-dimethylindolizin-7-amine (D1) (0.1 g, 0.3 mmol, single diastereomer) in 3 ml of iPrOH, 4,4-dimethyl-6-fluoro-4H-benzo[b]tetrazolo[1,5-d][1,4]oxazin-8-amine (0.093 g, 0.4 mmol) and 4N HCl in dioxane (0.1 ml) were added. The reaction mixture was heated to 100° C. in a sealed vial for 12 hours. LCMS analysis of the crude reaction mixture indicated the completion of the reaction. The crude product was purified by column chromatography to give 0.12 g (Yield=72%) of the product as a mixture of two enantiomers.
