Methoxyl silica gel was prepared readily by the treatment of silica chloride with methanol. By using methoxyl silica gel as a dehydrating agent, carboxylic acids reacted with methanol in the presence of a protonic acid such as 12‐phosphotungstic acid afforded the corresponding methyl esters in excellent yields.
