In analogy to example 20.a tert-butyl (S)-4-[(3-chloro-phenylamino)-methyl]-2,2-dimethyl-oxazolidine-3-carboxylic acid tert-butyl ester was reacted with p-anisaldehyde dimethyl acetal to give (S)-4-{[(3-chloro-phenyl)-(4-methoxy-benzyl)-amino]-methyl}-2,2-dimethyl-oxazolidine-3-carboxylic acid tert-butyl ester. White solid. MS (ISP): 463.1 ([{37Cl}M+H]+), 461.1 ([{35Cl}M+H]+)
