실험 절차

To a solution of (3R)-2-(tert-butoxycarbonylamino)-3-ethyl-5-methylnon-8-enoic acid (2 g, 6.38 mmole) in dichloromethane (20 mL) was added DIPEA (1.93 mL, 19.19 mmole), HATU (2.42 g, 6.38 mmole) followed by (2S,4R)-methyl 4-hydroxypyrrolidine-2-carboxylate (1.15 g, 6.38 mmole) at room temperature. The reaction mixture was stirred at room temperature for 2 h. The reaction mass was diluted with DCM and washed with water. The organic layer was dried over anhydrous Na2SO4 and concentrated under reduced pressure to get crude compound. The crude compound was taken to the next step without further purification (1.5 g, 53.4%). MS: MS m/z 441.6 (M++1)
