Participants

Reaction Steps

Add sodium triacetoxyborohydride (0.2301 g, 1.086 mmol) to a stirred solution of 6-[4-(3-oxo-butyl)-phenoxy]-nicotinamide (0.2051 g, 0.7214 mmol), benzylamine (0.079 mL, 0.723 mmol), glacial acetic acid (0.045 ml 0.786 mmol), and 1,2-dichloroethane (7 mL). Stir the reaction for 18 h at room temperature under nitrogen. Add methanol (1.5 mL) and load the reaction mixture directly onto a 2 g prepacked SCX cartridge. Wash the cartridge with methanol (100 mL) and elute the product off of the cartridge with 2 M ammonia in methanol (50 mL). Concentrate the eluant on a rotary evaporator to yield 0.1863 g (69%) of 6-[4-(3-benzylamino-butyl)-phenoxy]-nicotinamide: HPLC (30/70 to 90/10 ACN/(0.1% TFA in water) Zorbax SB-Phenyl Column 4.6 mm×15 cm×5 micron: Retention time: 4.09 minutes, Purity: 99.9%; mass spectrum (ion spray): m/z=376.4 (M+1).
