Abstract
PURPOSE: To obtain the titled compound useful as an intermediate for the production of pharmaceuticals, agricultural chemicals, etc., easily in high yield, by reacting a 1,2,3-trinhydroxybenzene derivative with dimethyl sulfate in the presence of boric acid and an alkali while controlling the amount of water used as a solvent.
CONSTITUTION: The objective compound is produced by reacting the 1,2,3- trihydroxybenzene derivative of formula (A is H, carboxyl or COOR1; R1 is lower alkyl) with dimethyl sulfate in the presence of boric acid salt (preferably 0.8W1.5mol per 1mol of the compound of formula) and an alkali (e.g. sodium hydroxide, etc., in an amount of e.g. 0.5W2mol per 1mol of the raw material) in ≤30ml, preferably 5W25ml of water (based on 1g of the compound of formula) to effect the conversion of the compound to monomethyl ether. The amount of the dimethyl sulfate is e.g. 0.5W2mol per 1mol of the raw material.
