4-Pentylbenzoyl chloride → Benzoic acid, 2-chloro-4-[(4-pentylbenzoyl)oxy]-, 4-pentylphenyl ester

Participants

Reaction Steps

A mixture of 4-pentylphenyl 2-chloro-4-hydroxybenzoate (0.0075 mole) prepared as in Example 1 and p-pentylbenzoyl chloride (0.0075 mole) in pyridine (35 ml.) is stirred at room temperature for 5 hours. The reaction mixture is then poured into ice-water. The product is filtered and washed with water to give 4-n-pentylphenyl 2-chloro-4-(4-pentylbenzoyloxy)benzoate (3.1 g., 84%), m.p. 38°-122°C. The analytical sample, m.p. 39°-122°C is obtained by chromatography on Florisil and crystallization from ethanol. The theoretical values calculated for C30H33ClO4 and the values actually found are as follows:
