Procedure
With stirring, 37.52 g (446.6 mmol) of sodium bicarbonate were added to 50 g (406 mmol) of 2-amino-4-methylphenol in 250 ml of 2-methoxyethanol. 84.4 g (446.6 mmol) of 4-chloromethylbenzoyl chloride, dissolved in 250 ml of 2-methoxyethanol, were then added dropwise to the solution over 15 min. During this time, an increase in reaction temperature of from room temperature to 40° C. was observed. After 4 hours of stirring, 1 liter of water and 10 ml of concentrated hydrochloric acid were added to the reaction mixture. The crystals formed were filtered off and dried under reduced pressure. This gave 116 g of the target compound which were reacted further without further purification.
