Procedure
1.80 g of 6-methylveratraldehyde was treated with 2 g KOH, 1.4 ml 95% hydrazine, and 20 ml diethylene glycol in the manner described in the preparation of 3,4-dimethoxytoluene to give a quantitative yield of 4,5-dimethylveratrole as a cream colored solid. An analytical sample was sublimed (60°/0.05 mm Hg) to give a white powder, mp 41°-42°(Lit. 42.5°). Nmr (δ): 2.19 (s, 6H), 3.85 (s, 6H), 6.66 (s, 2H).
