Participants

Reaction Steps

A mixture of 50 mg (0.087 mmol) 6-(5-acetyl-thiophen-2-yl)-N-(3,5-bis-trifluoromethyl-benzyl)-N-methyl-4-o-tolyl-nicotinamide (Example 38), 7 mg (0.2 mmol) sodium borohydride in 1 ml ethanol and a small amount of tetrahydrofuran was stirred at room temperature for 2 h. The reaction was quenched by addition of water, followed by 1 N aqueous hydrochloric acid solution. The mixture was basified with sodium carbonate and extracted with 3 portions of ethyl acetate. The combined organic extracts were dried with sodium sulfate, filtered and concentrated to give 48 mg (96%) of the title compound as a slightly yellow solid.
