Reaction Steps

A suspension of an aqueous solution of 5.2% sodium hydroxide (630 g), 2,5-xylenol (100 g), an aqueous solution of 60% glyoxal dimethyacetal (213 g) and water (200 g) was heated at 55° C. for 5 hours with stirring. The reaction mixture was cooled in an ice bath, and to the mixture were added acetonitrile (90 g) and 7.4% hydrochloric acid (380 g) successively. The precipitating crystals were filtered to give 4-(1-hydroxy-2,2-dimethoxyethyl)-2,5-dimethylphenol (150 g).
