N2-{[({3-(4-Chlorophenyl)-5-oxo-4-[(1E)-3,3,3-trifluoroprop-1-en-1-yl]-4,5-dihydro-1H-1,2,4-triazol-1-yl}acetyl)amino][2-(trifluoromethyl)phenyl]acetyl}-2-methylalaninamide → N2-{({[3-(4-Chlorophenyl)-5-oxo-4-(3,3,3-trifluoropropyl)-4,5-dihydro-1H-1,2,4-triazol-1-yl]acetyl}amino) [2-(trifluoromethyl)phenyl]acetyl}-2-methylalaninamide

Reaction Steps

A solution of 25 mg (39 μmol) of the compound of Example 31 in 10 ml of methanol was hydrogenated in an H-Cube fitted with a platinum cartridge (5% Pt/C) (continuous-flow hydrogenation apparatus from Thales Nano, Budapest, Model HC-2-SS) at a flow rate of 1 ml/min, at 60° C. and under hydrogen at standard pressure. The resulting solution was freed from methanol on a rotary evaporator, and the residue was dissolved in 2 ml of acetonitrile and purified by preparative HPLC [Method 7]. This gave 8 mg (32% of theory) of the title compound.
