该中间体在本合成路线中的序号：(XIII)Coupling of N-Boc-L-methionine (VIII) with 3-chlorobenzylamine (IX) using PyBOP provided amide (X). Methylation of the sulfide group of (X) with iodomethane gave rise to the sulfonium salt (XI), which was further cyclized to pyrrolidinone (XII) by treatment with lithium bis(trimethylsilyl)amide in cold THF. Acid deprotection of the Boc group of (XII) furnished amine (XIII). This was finally subjected to reductive alkylation with aldehyde (VII) in the presence of sodium cyanoborohydride to provide the corresponding (imidazolylmethyl)amine.
