P-Cresol → Pentanoic acid, 4-methylphenyl ester

Participants

Reaction Steps

Pentanoyl chloride (39.8 g) in dichloromethane (50 ml) was added slowly to a solution of p-cresol (32.4 g) and triethylamine (36.4 g) in dichloromethane (250 ml) with ice cooling. After 1 hour the reaction mixture was washed with brine, dried over magnesium sulfate, filtered and evaporated under reduced pressure to give 4-methylphenyl pentanoate.
