YieldReaction ConditionsOperation in experiment
65%; 26% In o-xylene; for 16h;Heating / reflux; Ethyl propiolate (804 mg) was added to the oxylene (15 mL) solution of tetrahydropyridino[1,2-c][1,2,3]oxadiazolone (1.04 g) under a nitrogen atmosphere and refluxed for 16 h. The solution was concentrated under a reduced pressure. The residue was applied to silica gel column chromatography, then the column was eluted with n-hexane-AcOEt (2/1-1/1). The titled compound was obtained as yellow oil (871 mg, 65%), and 4,5,6,7-tetrahydropyrazolo[1,5-a]pyridine-3-carboxylic acid ethyl ester was obtained as yellow oil (345 mg, 26%). 1H NMR (CDCl3) delta1.39 (t, 3H, J=7.1 Hz), 1.84-1.91 (m, 2H), 2.02-2.09 (m, 2H), 2.82 (t, 2H, J=6.4 Hz), 4.22 (t, 2H, J=6.2 Hz), 4.39 (q, 2H, J=7.1 Hz), 6.53 (s, 1H).
