Patent ID: 10981940

Abstract:
The invention is to develop a protecting group that does not solidify or insolubilize a compound in which a functional group has been protected, and facilitates separation and purification after a reaction. Disclosed is a trityl compound represented by General Formula (1): wherein Y represents a hydroxy group or a halogen atom; at least one of R1 to R15 represents a group represented by Formula (2): —O—R16—X-A  (2) while the other groups 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;       wherein R18, R19, and R20, which may be identical or different, each represent a linear or branched alkyl group having 1 to 6 carbon atoms, or an aryl group which may have a substituent.
