実験手順

1-Phenyl-propan-2-one (40.8 g) was dissolved in 200 ml of MeOH. Formaline (37%) (79 mL), piperidine (4 ml) and HOAc (4 ml) where added and de reaction was stirred for 3 h at 60° C. The reaction mixture was evaporated to dryness under reduced pressure. The residue was taken up in diethyl ether, and extracted with water. The organic layer was washed with 1M HCl, dried over MgSO4 and evaporated under reduced pressure to yield 36.3 g of a yellow liquid. 1H NMR (400 MHz, CDCl3) δ 2.41 (s, 3H), 5.87 (s, 1H), 6.18 (s, 1H), 7.24-7.40 (m, 5H).
