실험 절차

1.1 equiv of carbonyl diimidazole is added to a solution of benzoic acid 178 (200 mg) in tetrahydrofuran (5 mL); the reaction is stirred at room temperature for 3 h. After this time N-piperonyl-N-benzylamine (0.25 g) is added in one portion. After 30 min, the reaction is filtered, diluted with ether and washed with water. The organic layer is dried (Na2SO4) and purified over column chromatography to provide the desired product (390 mg). The proton NMR displays a typically doubled pattern. 1H (CDCl3) 3.83 and 4.32 (two doublets, J=16 Hz, 1H), 3.91 (two doublets, J=8 Hz, 1H), 4.18 two doublets (J=6 Hz, 1H), 5.0 and 5.1 (two doublets, J=14 Hz, 1H), 5.93 and 5.98 (s and doublet, J=2 Hz, 2H, OCH2O), 6.35-6.40 (m, 2H), 6.51 (d, J=4 Hz, 0.5H), 6.4 (m, 1.5H), 7.0-7.88 m, 15H). LC-MS 412.3.
