実験手順

Add three-angstrom molecular sieves to a stirred solution of 6-[4-(2-amino-ethyl)-phenoxy]-nicotinamide (0.1000 g, 0.3887 mmol) (compound of example 33), 2-methoxybenzaldehyde (0.047 mL, 0.39 mmol), and methanol (5 mL). Agitate the reaction for 18 h on a platform shaker at room temperature. Add sodium borohydride and agitate for 1 h at room temperature. Filter to remove the molecular sieves and load the reaction mixture directly onto a 10 g prepacked SCX cartridge. Flush with methanol (150 mL) and elute the product off the SCX cartridge with 2 M ammonia in methanol (50 mL). Concentrate on a rotary evaporator to give 0.1253 g (85%) of 6-{4-[2-(2-methoxy-benzylamino)-ethyl]-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: 4.14 minutes, Purity: 97.9%; mass spectrum (ion spray): m/z=378.1 (M+1).
