반응 단계

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 12 ml of DMF, and the mixture was stirred at RT for 30 min 234 mg (1.88 mmol) of beta-alaninamide hydrochloride and 436 μl (2.50 mmol) of N,N′-diisopropylethylamine were added, and the mixture was stirred for another 1 h. The mixture was diluted with ethyl acetate and washed four times with water. The organic phase was dried over sodium sulphate and freed from the solvent on a rotary evaporator. The residue was dried under high vacuum. This gave 446 mg (91% of theory) of the title compound.
