Reaction Steps

Combine tyramine (5.0 g, 36.4 mmol), benzaldehyde (3.8 ml, 37.2 mmol) in MeOH (46 mL), heat at reflux for 2 h. Cool the mixture at 0° C. and add NaBH4 (1.44 g, 38.2 mmol). Stir at room temperature overnight. Remove most of MeOH, add H2O and stir for 2 h. Filter the mixture and wash the white solid with water. Dry the solid precipitate under vacuum at 40° C. overnight to afford the title compound (7.53 g, 91%). Electrospray MS M+1 ion=228. 1H-NMR (methanol-d4, 300 MHz): 7.40-7.20 (m, 5H), 7.03-6.95 (m, 2H), 6.73-6.65 (m, 2H), 3.75 (s, 2H), 2.85-2.65 (m, 4H).
