摘要： Provided is a method of efficiently producing a solution composition containing a monoetherified product (III) using a hydroquinone compound (I) and a hydroxyl group-containing etherifying agent (II). The method of producing a solution composition includes: a step (1) of reacting a hydroquinone compound (I) and a hydroxyl group-containing etherifying agent (II) in a two-phase system including an alkaline aqueous solution and a hydrophobic ether solvent, and in the absence of a phase transfer catalyst and a hydrophilic organic solvent; and a step (2) of separating and removing an aqueous phase of a two-phase reaction liquid by liquid separation, and washing an organic phase using an aqueous solution containing a neutral inorganic salt and a hydroxide of an alkali metal, or the like.

摘要： A novel agent for introducing a protecting group for a hydroxy group and/or a mercapto group that can be introduced and removed under mild conditions is provided. The agent for introducing a protecting group for a hydroxy group and/or mercapto group of a substrate compound having the hydroxy group and/or mercapto group is represented by the following formula (I), wherein A represents a ring structure having 1 to 5 rings in which two carbon atoms of an adjacent benzene ring are included, the ring structure comprises a substituted or unsubstituted five-membered ring or six-membered ring and optionally include a heterocycle; each of R 1 , R 2 , R 3 , and R 4 is independently a hydrogen atom or a linear or branched alkyl group having 1 to 5 carbon atoms; and X is a halogen atom or OSO 2 R 5 (R 5 = an aryl group or an alkyl group) .
