Procedure

Methyl (2R)-5-[5-[{2-[3,5-bis(trifluoromethyl)phenyl]-2-methylpropanoyl}(methyl)amino]-4-(4-fluoro-2-methylphenyl)pyridin-2-yl]-2-methyl-3,4-dihydro-2H-pyrrole-2-carboxylate (Intermediate 23 1.06 Kg) was suspended in 20.44 L of 7M ammonia in methanol. The mixture was gently stirred for at least 5 days at 20° C. The mixture was concentrated by half by distillation at atmospheric pressure. The solution obtained was then cooled to 40° C. and stirred for 1 h. The slurry obtained was then cooled to 0° C. over 3 h and aged at 0° C. for 2 h. The title compound was then isolated by filtration and the cake washed with ice cold methanol (1.1 L). The wet cake was dried at 40° C./vacuum to yield the title compound (841.3 g).
