Reaktionsschritte
Using the procedure of Eample I, 2,4-dimethoxybenzoyl chloride was allowed to react with pentaerythritol in the molar ratio of 4:1. The reaction gave a 78% yield of white crystalline product having a melting point of 125°-126.5° C. and the infrared spectrum was a consistent with the expected tetraester with no hydroxyl band and an ester carbonyl band at 5.85μ (s).
