Reaction Steps

4-Vinyl pyridine (50 mmol), glacial acetic acid (3 ml), cyclopropylamine (4.28 g, 75 mmol) and water (12.8 ml) were heated at 50° C. for 22 hours. The crude reaction products were added to a vigorously stirred mixture of ether and saturated aqueous NaHCO3. After partitioning, the organic phase was washed with water, brine and dried. Filtered and solvents removed under vacuum. The residue was further distilled under vacuum (Kugelrohr) and the product amine collected. NMR (CDCl3) 8.45 (m, 2H), 7.05 (m, 2H), 2.93 (m, 2H), 2.73 (m, 2H), 2.07 (m, 1H), 1.37 (m, 2H), 1.25 (m, 2H); m/z 163.17.
