実験手順

To a solution of 7.125 g (56.75 mmol) of glycine methylester hydrochloride in 60 ml of dioxane and 24 ml of H2O, 15 ml (107.8 mmol) of Et3N and then a solution of 10 g (40.53 mmol) of 4-cyclopropylmethoxy-benzenesulfonyl chloride in 10 ml of dioxane are added dropwise at 0–5° C. After stirring for 3 h at r.t., the reaction is quenched with ice water and the mixture is extracted with AcOEt. The combined extracts are washed with H2O, brine, dried over MgSO4 and concentrated under reduced pressure to give the title compound as a colorless solid; 1H-NMR (400 MHz, CDCl3): 0.3–0.40 (m, 2H), 0.65–0.72 (m, 2H), 1.20–1.35(m, 1H), 3.65 (m, 3H), 3.77 (d, 2H, J=5.04 Hz), 3.86 (d, 2H, J=7.08 Hz), 4.98 (brs, 1H), 6.96 (d, 2H, J=8.52 Hz), 7.77 (d, 2H, J=8.52 Hz).
