5-Amino-N-(2-{[ethyl(phenylmethyl)amino]methyl}-3,3,3-trifluoro-2-hydroxypropyl)-1-(4-fluorophenyl)-1H-pyrazole-4-carboxamide → 5-Amino-N-{2-[(ethylamino)methyl]-3,3,3-trifluoro-2-hydroxypropyl}-1-(4-fluorophenyl)-1H-pyrazole-4-carboxamide

Participants

Reaction Steps

A solution of 5-amino-N-(2-{[ethyl(phenylmethyl)amino]methyl}-3,3,3-trifluoro-2-hydroxypropyl)-1-(4-fluorophenyl)-1H-pyrazole-4-carboxamide (0.39 g, 0.813 mmol) in ethanol (35 ml) was stirred under an atmosphere of hydrogen over Pearlman's catalyst (45 mg) for 7 hours (32 ml of hydrogen taken up). The catalyst was filtered off and the filtrate was evaporated to give the title compound (0.313 g) as a white solid.
