Triethylamine → Benzoic acid N'-(3,3-diphenyl-propionyl)-N'-isopropyl-hydrazide

Participants

Reaction Steps

A solution of 3,3-diphenylpropionic acid (127 mg, 0.56 mmoles) and benzoic acid N′-isopropyl-hydrazide (100 mg, 0.56 mmoles) in DMF (5 mL) was treated with triethylamine (0.23 mL, 1.68 mmol), HOBT (91 mg, 0.67 mmoles) and EDCI (129 mg, 0.67 mmol) at room temperature for 18 h. The reaction mixture was partitioned between water and dichloromethane. The organic layer was washed with water, dried over sodium sulfate, filtered and concentrated. The crude was absorbed on silica and purified on a silica gel column with a 30-50% ethyl acetate/hexanes gradient to afford the product as a solid (59 mg, 27%). LC-MS m/e 387.26 (M+H+)
