Reaction Steps

A mixture of (7R,8aS)-N-(2-chloro-5-fluoropyrimidin-4-yl)-5,5-dimethyloctahydroindolizin-7-amine (0.2 g, 1.0 eq, 0.6 mmol), tert-butyl (3S,4S)-4-(4-amino-2-chlorophenoxy)-3-fluoropiperidine-1-carboxylate (0.2 g, 1.0 eq, 0.64 mmol) and PTSA (0.1 g, 0.9 eq, 0.6 mmol) was taken in iPrOH (10 mL) and heated at 100° C. for over night. After 18 hours of heating, reaction mixture was cooled to room temperature and PTSA (1.0 eq) was added to complete the deprotection of the Boc group. Then the reaction mixture was heated at 100° C. for 3 hours while stifling and cooled to room temperature. The volatiles were removed under vacuum to leave a crude solid. 4N HCl in dioxane (5 mL) was added to the crude mixture to ensure complete dprotection of the Boc group and the mixture was concentrated to dryness. Work-up and purification conditions used were the same as in Example 89 above for Compound 119, and gave the product as a solid in 50% yield.
