実験手順

3.7 g (19 mmol) of 1-(2-chlorophenyl)-1,2-dihydro-5H-tetrazol-5-one, 3.6 g (19 mmol) of N-ethyl-N-(tetrahydro-2H-pyran-4-yl)carbamoyl chloride and 2.6 g (21 mmol) of 4-dimethylaminopyridine in 150 ml of toluene were heated under reflux for 5 hours. The organic phase was washed with water, dried over magnesium sulfate, filtered and concentrated. The residue was purified by silica gel column chromatography (eluent hexane/ethyl acetate 2:1). Yield 5.5 g. 1H NMR (270 MHz, in CDCl3): δ=1.20-1.40 (m, 3H), 1.80-2.05 (m, 4H), 3.30-3.60 (m, 4H), 3.70-4.50 (m, 3H), 7.40-7.60 (m, 4H).
