Procedure
In a sealed tube a solution of methyl(5S,7R)-8-{[{[3,5-bis(trifluoromethyl)phenyl]methyl}(methyl)amino]carbonyl}-7-(4-fluoro-2-methylphenyl)-1,8-diazaspiro[4.5]decane-2-carboxylate (Intermediate 22, 63 mg, 0.107 mmol) in 7 N ammonia solution in MeOH (5 ml, 35.0 mmol) was shaken overnight. The solvent was evaporated to dryness and the crude was purified by flash-chromatography [Si cartridge (5 g), from 1:0 to 95:5 DCM/MeOH] to give the title compound (53.5 mg, 0.093 mmol, 87% yield) as a white solid. 1H NMR (500 MHz, DMSO-d6) δ ppm 7.95 (s, 1H) 7.61 (s, 2H) 7.24-7.32 (m, 1H) 7.15-7.24 (m, 1H) 6.98-7.05 (m, 1H) 6.92 (d, 1H) 6.79 (t, 1H) 4.65 (d, 1H) 4.36 (d, 1H) 4.15 (d, 1H) 3.44-3.59 (m, 1H) 3.38 (d, 1H) 2.93 (s, 3H) 2.75 (t, 1H) 2.65 (br. s., 1 H) 2.33 (s, 3H) 1.99-2.21 (m, 1H) 1.51-1.93 (m, 6H) 1.45 (t, 1H); HPLC: Rt 4.88 mins; MS: m/z=575 [M+H]+.
