実験手順

To a solution of 79.5 g (323.2 mmol) of the compound of stage 3.2, 80.9 ml (581.6 mmol) of Et3N and 1.97 g (16.1 mmol) of DMAP in 1000 ml of CH2Cl2, a solution of 99.6 g (404 mmol) of 4-cyclopropylmethoxy-benzenesulfonyl chloride in 150 ml of CH2Cl2 is added and stirred for 60 min. at 0–5° C. After stirring for additional 18 h at r.t., the reaction mixture is quenched with ice water and extracted with CH2Cl2. The combined extracts are washed with H2O, brine, dried over MgSO4 and concentrated under reduced pressure. The residue is purified by CC on silica gel (n-Hexane:AcOEt=4:1˜2:1) to give the title compound as colorless solid; 1H-NMR (400 MHz, CDCl3): 0.35–0.45 (m, 2H), 0.65–0.75 (m, 2H), 1.25–1.35 (m, 1H), 3.58 (s, 3H), 3.87 (d, 2H, J=7.04 Hz), 3.94 (s, 2H), 4.52 (s, 2H), 6.99 (d, 2H, J=7.04 Hz), 7.37 (d, 2H, J=8.56 Hz), 7.81 (s, 2H), 7.82 (d, 2H, J=7.04 Hz), 8.02 (d, 2H, J=8.56 Hz).
