Patent ID: 8475998

Claim:
A compound synthesis method comprising: bonding a first compound that includes an acid-labile protecting group to a substrate to form a first film; forming a second film on the first film using an acid-transfer composition, the acid-transfer composition including (A) a polymer that includes a structural unit shown by a following formula (1) and a structural unit shown by a following formula (2), (B) a photoacid generator including a compound shown by a following formula (3), (C) a sensitizer including a compound shown by a following formula (4), and (D) a solvent which does not include ketone; exposing the second film to remove the protecting group from the first compound under an exposed area of the second film; transferring an acid generated in the exposed area of the second film to the first film; removing the second film after being exposed; and bonding a second compound to the first compound from which the protecting group has been removed to synthesize a compound in which the first compound and the second compound are bonded, wherein R 1 represents a hydrogen atom or a methyl group, and each of R 2 and R 3 independently represents a hydrogen atom, a linear or branched hydrocarbon group having 1 to 10 carbon atoms, or a cyclic hydrocarbon group having 3 to 10 carbon atoms, or each of R 2 and R 3 independently represents a hydrogen atom, a linear or branched hydrocarbon group having 1 to 10 carbon atoms, or a cyclic hydrocarbon group having 3 to 10 carbon atoms, and R 2 and R 3 bond to form a 3 to 10-membered monocyclic hetero ring, or bond via at least one hetero atom selected from a nitrogen atom, an oxygen atom, a sulfur atom, and a selenium atom to form a 4 to 10-membered monocyclic hetero ring, wherein R 1 represents a hydrogen atom or a methyl group, and R 2 represents a monovalent organic group, wherein each of R 1 and R 2 independently represents an alkyl group or a halogen atom, and each of n and m is independently an integer from 1 to 4.
