실험 절차

To a stirred solution of acid from step 6 (100 mg, 0.5 mmol), (2R,3S)-3-amino-4-(3,5-difluorophenyl)-1-[(3-ethylbenzyl)amino]butan-2-ol (190 mg, 0.5 mmol), and HATU (175 mg, 0.5 mmol) in methylene chloride (5 mL) was added N,N-diisopropylethylamine (280 μL, 1.6 mmol). The reaction mixture was stirred at room temperature for 18 h. The reaction mixture was partitioned between methylene chloride and water. The organic layer was washed with water, dried (sodium sulfate), filtered, and concentrated under reduced pressure to afford a crude oil. Purification by flash column chromatography (silica, gradient 95:5 to 92:8 methylene chloride/methanol) provided the title compound (60 mg): mp 45-50° C.; ESI MS m/z 537 [M+H]+.
