الإجراء التجريبي

Following the procedure of Example I, 3,4-dimethoxybenzoyl chloride was allowed to react with 1,1,1-trimethylolethane in the molar ratio of 3:1. The product was obtained in 90% yield as a glassy substance which slowly crystallized after being precipitated from methanol at dry-ice temperature. The triester is a white crystalline material, mp 105°-106° C., with an ester carbonyl band at 5.85μ. The proton magnetic resonance spectrum was consistent with the title compound.
