Hide Experimental Procedure

III:3,4,5-trimethoxybenzaldehyde (from 3,4,5-trimethoxybenzyl alcohol)

EXAMPLE III 3,4,5-trimethoxybenzaldehyde (from 3,4,5-trimethoxybenzyl alcohol) 33.9 g (0.34 moles) of chromic anhydride are slowly dissolved under efficient stirring in 500 ml of glacial acetic acid and heating at 90°-100° C. To this oxydation mixture, g 19.8 of 3,4,5-trimethoxy benzyl alcohol dissolved in 160 ml of glacial acetic acid are very slowly added under continuous stirring. The mixture is kept reacting during 30' after the end of the addition and is then cooled, diluted with water and extracted with CHCl3 (3 fractions of 200 ml each). The organic fractions are then joined and concentrated under a vacuum. Obtained are g 17.60 (90percent). M.P. 38°-40° C.; B.P., 168°-170° C./12 mm. NMR spectrum: (CDCl3) δ 9.82 (s, 1H, --CHO); 7.1 (s, 2H, aromatics) and 3.95 (s, 9H, 3 OCH3).
