Reaction Steps

To a mixture of methyl 2-(trans-4-(cyclopropylamino)cyclohexyl)acetate (0.150 g, 0.710 mmol) in CH2Cl2 (2.5 mL) were added diisopropylethylamine (0.173 ml, 0.994 mmol), 4-chlorobenzoic acid (0.0866 ml, 0.852 mmol), and bis(2-oxo-3-oxazolidinyl)phosphinic chloride (0.470 g, 1.85 mmol) sequentially. The mixture was stirred at room temperature overnight, diluted with CH2Cl2 (50 mL), and then washed with 10% Na2CO3 and brine. The organic layer was dried over Na2SO4 and concentrated in vacuo. The crude product was purified through silica gel chromatography eluting with 18%-25% EtOAc-hexane. The desired amide product was obtained as a colorless oil (0.199 g). MS: 350 (M+1), C19H24ClNO3.
