반응 단계

Isopropyl bromide (19.0 mL, 200 mmol) was added to a suspension of K2CO3 (42.0 g, 302 mmol) and isovanillin (23 g, 151.3 mmol) in DMF (100 gmL) and the stirring slurry heated to 80° C. for 13 h. The reaction mixture was then cooled to room temperature, diluted with ether (200 mL) and washed with H2O (4×200 mL), dried (MgSO4) and concentrated under reduced pressure giving the title compound as a slightly tan oil (29.3 g, 100%) which required no further purification. The spectra of this material are identical with those previously reported (H. Ishii, I.-S. Chen and T. Ishikawa J. Chem. Soc., Perkin Trans. 1, 1987, 671.).
