摘要： The purpose of the present invention is to provide a protecting group which improves the solubility of a compound having a functional group protected with the protecting group in an organic solvent and which is easily separated and purified after a reaction with avoiding solidification or insolubilization. Provided is a benzyl compound represented by Formula (1) where X1 represents —CH2OR14 (where R14 represents a hydrogen atom, a halogenocarbonyl group, or an active ester-type protecting group), —CH2NHR15 (where R15 represents a hydrogen atom, a linear or branched alkyl group having 1 to 6 carbon atoms, or an aralkyl group), a halogenomethyl group, a methyl azide group, a formyl group, or an oxime; and at least one of R1, R2, R3, R4, and R5 is a group represented by Formula (2), and the remainders each represent a hydrogen atom, a halogen atom, an alkyl group having 1 to 4 carbon atoms, or an alkoxy group having 1 to 4 carbon atoms, where R6 represents a linear or branched alkylene group having 1 to 16 carbon atoms; X2 represents O or CONR16 (where R16 represents a hydrogen atom or an alkyl group having 1 to 4 carbon atoms); and A represents a group represented by Formula (3), (4), (5), (6), (7), (8), (9), (10), (11), (12), or (13).
