Procedure

360 mg (1.88 mmol) of EDC were added to a mixture of 400 mg (1.25 mmol) of [(tert-butoxycarbonyl)amino][3-(trifluoromethyl)phenyl]acetic acid and 254 mg (1.88 mmol) of HOBt in 10 ml of DMF, and the mixture was stirred at RT for 20 min. The resulting solution was added dropwise to a solution of 168 mg (1.88 mmol) of 2-amino-2-methyl-1-propanol in 2 ml of DMF. The reaction mixture was stirred at RT for 20 min. For purification, 1 ml of 1N hydrochloric acid was added and the entire reaction mixture was separated by preparative HPLC [Method 6]. The appropriate fraction was concentrated on a rotary evaporator and the residue was dried under high vacuum. This gave 364 mg (74% of theory) of the title compound.
