Triethylamine → 4-(3-Fluoro-4-methoxy-phenyl)-1-methanesulfonyl-1,2,3,6-tetrahydro-pyridine

Participants

Reaction Steps

4-(3-Fluoro-4-methoxy-phenyl)-1,2,3,6-tetrahydro-pyridine hydrochloride salt (462.00 mg, 1.90 mmol) is suspended in dichloromethane (10 mL). Triethylamine (479.58 mg, 660.57 μL, 4.74 mmol) and methanesulfonyl chloride (260.59 mg, 176.07 μL, 2.27 mmol) are added and the reaction is capped and stirred at room temperature for 16 h. The reaction is partitioned between dichloromethane and water. The aqueous layer is extracted with dichloromethane. The combined organic layers are washed with brine, dried over magnesium sulfate, filtered, and concentrated to dryness. The crude material is purified by chromatography using a 5 g silica gel cartridge eluting with dichloromethane to provide 349 mg of the title compound as a white solid. MS (m/z) 286 (M+1).
