The major isomer from Step A in Example 50 (45.1 mg, 0.197 mmol) was dissolved in DCM (1.0 mL) and 4N HCl in dioxane (492 μL, 1.97 mmol) was added. The reaction mixture was stirred at ambient temperature for 1 hour and was concentrated to afford 4-amino-1-methylcyclohexanol (major isomer). The 4-amino-1-methylcyclohexanol was reacted with (R)-5-(2-(2,5-difluorophenyl)pyrrolidin-1-yl)pyrazolo[1,5-a]pyrimidine-3-carboxylic acid (Preparation C) according to the procedure outlined in Example 1 to provide the title product as a white solid (10.7 mg, 38% yield). MS (apci) m/z=456.1 (M+H).
