Triethylamine → HCID 67448480, compound

Participants

Reaction Steps

540 μL (3.85 mmol) of triethylamine and 864 mg (2.69 mmol) of TBTU were added to a solution of 541.5 mg (2.69 mmol) of 1-tert-butoxycarbonylamino-cyclopropanecarboxylic acid in 45 mL DMF and the mixture was stirred for 5 min at RT. Then 800 mg (2.69 mmol) of 4-(4-methoxy-2-trifluoromethyl-phenoxy)-benzylamine (from 84a) was added and the mixture was stirred for 2 h at ambient temperature. The reaction mixture was filtered through Alox B, washed with DMF/MeOH=9/1 and the filtrate was evaporated down. 20 ml dichloromethane/trifluoroacetic acid/water=50/45/5 were added to the residue and the mixture was stirred for 1 h at RT. The reaction mixture was evaporated down, the residue was dissolved in dichloromethane and extracted with 10 mL of 1 M sodium hydroxide solution. The dichloromethane phase was separated off and evaporated down.
