Reaction Steps
30 g (168 mmol) of 3-(4-hydroxyphenyl)acrylic acid methyl ester, 29 g (210 mmol) of anhydrous K2CO3 and a spatula tip of KI were placed in 200 ml of dimethylformamide. 14.91 g (185 mmol) of 2-chloroethanol were added dropwise at 85° C. within 5 minutes while stirring. The batch was stirred at 85° C. for a further 3 days. Subsequently, the salts were filtered off and the filtrate was concentrated to dryness in a water-jet vacuum. 16.1 g of (E)-3-[4-[2-hydroxyethoxy]phenyl]acrylic acid methyl ester were obtained in the form of white crystals after recrystallization from i-propanol.
