Reaction Steps
A solution of 0.150 g (0.53 mmole) 1,3-dihydro-6-nitro-1-oxospiro[2H-indene-2,4'-piperidine] hydrochloride, 0.116 g (1.1 mmoles) 2-vinylpyridine, and 0.090 g (1.1 mmoles) sodium acetate in 1.5 ml of 1:1 methanol: water was heated at reflux for 8 hours. Ethanol was removed in vacuo. The aqueous residue was diluted with 3 ml saturated sodium bicarbonate solution and extracted with 2×10 ml ethyl acetate. The combined extracts were washed with 3 ml water brine, dried, and the solvent was removed in vacuo to give 0.195 g crude product. This was recrystallized from ethyl acetate to give 0.123 g (66%) product, m.p. 142°-144° C.
