Reaction Steps

In a sealed tube a solution of methyl (2R,5S,7R)-8-{[{(1R)-1-[3,5-bis(trifluoromethyl)phenyl]ethyl}(methyl)amino]carbonyl}-7-(4-fluoro-2-methylphenyl)-2-methyl-1,8-diazaspiro[4.5]decane-2-carboxylate (Intermediate 44, 70 mg, 0.113 mmol) in 7 N methanolic ammonia (5 mL, 35.0 mmol) was shaken at 40° C. for 5 days by PLS. Volatiles were removed in vacuo and the residue was purified by flash chromatography on silica gel using a SNAP 10 g as column and Dichloromethane/Methanol 98:2 as eluent affording the title compound (38 mg, 0.063 mmol, y=55.7%).
