Participants

Reaction Steps

Take up the mixture of 4-[4-(2-aminoethyl)phenoxy] benzenesulfonyl azide (0.210 g, 0.661 mmol) in methanol (9.9 mL). Add benzaldehyde (0.20 mL, 1.98 mmol) and 3 Å molecular sieves. Stir at room temperature overnight. Add NaBH4 (0.075 g, 1.98 mmol) and stir for 1.5 hours. Filter the reaction mixture and purify by flash 40 chromatography, eluting with 3% (2.0 M NH3 in methanol), 30% hexanes and 67% ethyl acetate to give the title compound (0.0696 g, 25.8%): TOF MS ES+ 383.1 (M+H)+, HRMS calcd for C21H23N2O3S 383.1429 (M+H)+, found 383.1436, time 0.33 min; TLC [silica gel 60 F254, 10% (2.0 M NH3 in methanol) in dichloromethane] Rf=0.31.
