5-Amino-2-methoxyphenol → 1-[(3-Hydroxy-4-methoxyphenyl)aminosulfonyl]-3,4,5-trimethoxybenzene

Participants

Reaction Steps

To a solution of 3,4,5-trimethoxybenzenesulfonyl chloride (500 mg, 1.88 nmol) in methanol (10 mL) was added 3-hydroxy-4-methoxyaniline (523 mg, 3.76 mmol) at ambient temperature. After stirring for 1 h, the reaction mixture was concentrated and the crude residue was purified by chromatography over silica to afford 430 mg (62%) of product as fine white needles, m.p. 145-146° C.
