実験手順
The product from Example 118B (154 mg, 0.72 mmol), p-toluenesulfonyl chloride (278 mg, 1.44 mmol), DMAP (17 mg, 0.14 mmol) in CH2Cl2 (20 mL) was treated with triethylamine (0.25 mL, 1.8 mmol) and stirred at room temperature for 16 hours. The mixture was concentrated under reduced pressure and the residue was chromatographed on silica gel eluting with 40% EtOAc/hexanes to provide the title compound. 1H NMR (CDCl3) δ 2.18-2.40 (m, 4H), 2.48 (d, 3H), 2.51-2.58 (m, 2H), 7.25-7.29 (m, 1H), 7.35-7.45 (m, 4H), 7.66-7.73 (m, J=17.63 Hz, 1H), 8.07 (dd, J=15.60, 8.48 Hz, 2H), 8.85 (d, J=8.48 Hz, 1H). MS (M+H)+ m/z 367
