실험 절차

A solution of 985 mg of (R)-2-[2-amino-2-(3-methyl-1,2,4-oxadiazol-5-yl)-ethylsulfanyl-methyl]-3-[dimethyl-(1,1,2-trimethyl-propyl)-silanyloxy]-5-methoxy-6-methyl-benzoic acid methyl ester and 237 mg of 2-fluoroimidazole hydrochloride in 5 ml of N,N-dimethylformamide were stirred under argon at 50° C. for 3 h. A second portion of 117 mg of 2-fluoroimidazole hydrochloride was added and stirring was continued for 6 h. The reaction mixture was cooled and the solvent evaporated in vacuo. The residue was purified by silica gel chromatography using methanol/dichloromethane (1:20, v/v) as eluent to yield 310 mg of (R)-3-hydroxy-2-[2-(imidazol-2-ylamino)-2-(3-methyl-1,2,4-oxadiazol-5-yl)-ethylsulfanylmethyl]-5-methoxy-6-methyl-benzoic acid methyl ester hydrochloride as yellow solid.
