実験手順
EDC (2.52 g, 13.16 mmol) was added to a solution of compound benzyl 2-hydroxyacetate (2.02 g, 12.15 mmol), 4-(cyclopropylmethoxy)-3-formylbenzoic acid (2.23 g, 10.13 mmol), and DMAP (247 mg, 2.03 mmol) in DCM (20 ml) at RT under nitrogen atmosphere. The mixture was stirred at RT overnight. The mixture was then diluted with DCM and washed with NaHCO3 sat. sol., HCl 0.1M and brine. The organic phase was dried over Na2SO4, and the solvent was evaporated. 2-(benzyloxy)-2-oxoethyl 4-(cyclopropylmethoxy)-3-formylbenzoate was obtained (3.73 g, quantitative yield).
