Benzoyl chloride (33.3 mg, 0.24 mmol) was added to a solution of 5-fluoro-3-(1-methyl-1,2,3,6-tetrahydro-4-pyridinyl)indole (Example 4b, 49.6 mg, 0.215 mmol), triethylamine (0.15 mL, 1.1 mmol) and DMAP (5 mg) in dichloromethane (2 mL). The mixture was stirred at room temperature prior to quenching with water and extraction into dichloromethane. The organic layer was washed with brine and dried over sodium sulfate. Purification by flash chromatography (silica gel, 2M methanolic ammonia in chloroform) yielded 1-benzoyl-5-fluoro-3-(1-methyl-1,2,3,6-tetrahydro-4-pyridinyl)indole (27.8 mg, 39%, HRMS-FAB+ for C21H20N2OF calculated MH+ : 335.15598; found: 335.15457).
