Procedure

Poured into a suspension of 150 mg of (2R,3S)-3-amino-4-(3,5-difluorophenyl)-1-({1-[3-(trifluoromethyl)phenyl]cyclopropyl}amino)butan-2-ol hydrochloride (2:1), 101 mg of 1-oxo-2-(1-propylbutyl)-1,2,3,4-tetrahydroisoquinoline-5-carboxylic acid, 4 mg of hydroxybenzotriazole and 76 mg of 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride in 6 cm3 of dichloromethane is 0.217 cm3 of N,N-diisopropylethylamine at a temperature close to 20° C. The solution is kept stirring for 24 h at a temperature close to 20° C. 15 cm3 of water are added to the reaction medium. The organic phase is washed with 5 cm3 of a saturated aqueous solution of sodium chloride, dried over magnesium sulfate and concentrated using a rotary evaporator under reduced pressure (5 kPa). The product obtained is purified by flash chromatography over silica (column: 15 g; particle size: 120-40 μm, spherical; flow rate: 10 cm3/min; eluent: 100% ethyl acetate). After concentrating the fractions under reduced pressure, 140 mg of N-[(1S,2R)-1-(3,5-difluorobenzyl)-2-hydroxy-3-({1-[3-(trifluoromethyl)phenyl]-cyclopropyl}amino)propyl]-1-oxo-2-(1-propylbutyl)-1,2,3,4-tetrahydroisoquinoline-5-carboxamide are obtained in the form of a colorless oil.
