Tetrahydrofuran → HCID 57847038, compound

Participants

Reaction Steps

A mixture of calcium chloride (88 mg, 0.8 mmol), sodium borohydride (60 mg, 1.6 mmol), tetrahydrofuran (2.5 ml) and ethanol (2.5 ml) was stirred under a nitrogen atmosphere under ice-cooling for 30 min. To the mixture was added methyl 6-oxo-6-[((1R,2S)-2-{[(3aR,4R,9bR)-4-phenyl-2,3,3a,4,5,9b-hexahydro-1H-pyrrolo[3,2-c]quinolin-1-yl]carbonyl}cyclohexyl)amino]hexanoate (106 mg, 0.20 mmol) under ice-cooling, and the mixture was stirred at room temperature for 16 hrs. Water was added, and the reaction mixture was extracted with ethyl acetate. The extract was dried over anhydrous Na2SO4. The solvent was evaporated under reduced pressure, and the obtained residue was subjected to column chromatography using basic silica gel and eluted with ethyl acetate to give the title compound (89 mg, 92%) as a white solid.
