Reaction Steps
A pressure-proof reaction vessel equipped with a stirrer was charged with 17.5 g (0.09 mole) of 4-acetoxy-2,3,5-trimethylphenol, 32.5 g (0.45 mole) of 2-methyl-2-propen-1-ol, 3.7 g (0.099 mole) of 80% paraformaldehyde and 2.7 g (0.045 mole) of acetic acid, and the mixture was reacted, with stirring, at 150° C. for 3 hours. However, the desired product 2,5,7,8-tetramethyl-6-acetoxy-2-hydroxy-methylchroman could not be obtained at all.
