3,5-Dimethyl-4-hydroxybenzaldehyde → HCID 23046188, compound

Participants

Reaction Steps

The hydroxyl group of 3,5-dimethyl-4-hydroxybenzaldehyde (2.3 g) was protected by use of 2-methoxyethoxymethyl chloride (3.4 g) in accordance with (production process 1), to thereby produce 3,5-dimethyl-4-methoxyethoxymethoxybenzaldehyde (2.7 g, yield: 62%). The thus-produced 3,5-dimethyl-4-methoxyethoxymethoxybenzaldehyde (2.0 g) and 3,4-dimethoxybenzyl cyanide (1.5 g) were subjected to condensation in accordance with process A of (production process 2), to thereby yield an MEM form of the target product. Subsequently, the protective group was removed from the MEM form in accordance with (production process 3), to thereby produce the target product (1.5 g, yield: 57%).
