实验步骤: 1-[(4-Fluoro-1-naphthyl)sulfonyl]-1,2,3,4-tetrahydroquinoline—Method E: To a stirred solution of 4-fluoronaphthalene-1-sulfonyl chloride (200 mg, 0.82 mmol) in DCM (1 ml) was added 1,2,3,4-tetrahydroquinoline (123 μl, 0.98 mmol) followed by pyridine (0.25 ml). The reaction mixture was stirred over night, diluted with DCM and washed with 1M HCl (3×3 ml). Subsequent drying of the organic phase using MgSO4, and removal of the solvents in vacuo afforded the title compound (280 mg, 100%) as a white solid. 1H NMR (CDCl3) δ 8.24–8.10 (m, 3H), 7.68–7.62 (m, 1H), 7.58–7.51 (m, 1H), 7.42–7.34 (m, 1H), 7.23–7.04 (m, 3H), 6.96–6.89 (m, 1H), 3.84–3.74 (m, 2H), 2.39–2.28 (m, 2H), 1.63–1.49 (m, 1H); MS m/z (M+1) 342. washed with 1M HCl (3×3 ml) Subsequent drying of the organic phase MgSO4, and removal of the solvents in vacuo

实验步骤: The compound was prepared according to Scheme 10 in a similar manner to the method for preparing 4-fluoro-naphthalene-1-sulfonyl chloride. Chlorosulfonic acid (2.65 g, 1.5 mL, 22.7 mmol) was stirred in a round-bottom flask cooled by a water bath at room temperature. 5-Fluoro-1,2,3,4-tetrahydro-naphthalene (0.62 g, 4.13 mmol) was added dropwise and the dark mixture was stirred for 30 minutes until gas evolution ceased. The reaction mixture was poured carefully over a mixture of ice (75 g) and dichloromethane (100 mL) and charged to a separatory funnel. The organic layer was separated, washed with brine and dried over MgSO4. Filtration and concentration in vacuo afforded a tan solid.
