Reaction Steps

To a stifling solution of tyramine (1 mM, 137 mg) and MeOH (5 mL) was added acetaldehyde in excess. Then excess NaBH3CN (1 mM, 62.8 mg) was added and the mixture stirred for 2 hours at r.t. After evaporating the solvent, methylene chloride (5 mL) was added and mixture was washed with H2O (3×5 mL). The mixture was dried over MgSO4, filtered, and evaporated to give the product in 72% yield as an orange oil. TLC (toluene:diethylamine, 4:1 v/v): RF=0.5. 1H NMR, δ: 9.48 (s, 1H), 7.14 (d, 2H), 6.70 (d, 2H), 2.85 (m, 2H), 2.60 (t, 2H), 250 (q, 2H), 2.1 (s, 1H), 1.1 (t, 3H). 13C NMR, δ: 167.5, 134.3, 130.2, 115.6, 48.2, 44.4, 35.6, 15.6. Anal. calcd for C10H15NO: C, 72.69; H, 9.15; N, 8.48%. Found; C, 72.50; H, 9.20; N, 8.50%.
