Reaction Steps
The title compound was prepared in a similar fashion to that of Example 367 A using the following amounts of reagents: 3-(5-cyano-1-perhydro-2H-pyran-2-yl-1H-indazol-3-yl)benzoic acid (800 mg, 2.29 mmol), cyclobutyl amine (738 μL, 8.64 mmol), HOBT (1.17 g, 8.70 mmol), EDAC.HCl (1.67 g, 8.70 mmol) in anhydrous THF (25.0 mL) and anhydrous DMF (7.0 mL). Precipitation from methanol and ethyl acetate with hexanes afforded the desired compound (826 mg, 72% yield) as an off-white powder. ES-MS (m/z) 401 [M+H]+.
