실험 절차

A solution of ((3R,4aR,12bS)-3-(benzyloxy)-9-(4-fluorophenyl)-3-(trifluoromethyl)-1,2,3,4,4a,5,6,7,9,12b-decahydrobenzo[6,7]cyclohepta[1,2-f]indazol-12b-yl)methanamine (34, R1=4-Fluorophenyl, R3=Trifluoromethyl, Rg=Benzyl) (82 mg, 0.153 mmol) in DCM (3 mL) was treated with TEA (0.021 mL, 0.153 mmol) and 3-chloro-propane-1-sulfonyl chloride (0.023 mL, 0.19 mmol) at rt under nitrogen for about 1 h. The organic layer was washed with 2N aq. HCl (2 mL), dried over Na2SO4, filtered and concentrated under reduced pressure. The residue was dissolved in DMF (2 mL) and added dropwise to a suspension of sodium hydride (60 wt % in oil, 7.6 mg, 0.30 mmol) in DMF (1 mL). The reaction was heated at about 50° C. for 2 h and then cooled to rt and concentrate under reduced pressure. The residue was purified on silica gel (4 g) using a gradient of 0-30% EtOAc in DCM. Product fractions were combined and concentrated to yield 2-(((3R,4aR,12bS)-3-(benzyloxy)-9-(4-fluorophenyl)-3-(trifluoromethyl)-1,2,3,4,4a,5,6,7,9,12b-decahydrobenzo[6,7]cyclohepta[1,2-f]indazol-12b-yl)methyl)isothiazolidine 1,1-dioxide (35, R1=4-Fluorophenyl, R3=Trifluoromethyl, Rg=Benzyl) (63 mg, 64%) as an oil. LC/MS, method 3, Rt=3.01 min, MS m/z 642 (M+H)+. The oil was used in step #2 without further purification.
