실험 절차

A mixture of 1-methylethyl[(2S,4R)-1-acetyl-2-methyl-6-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1,2,3,4-tetrahydro-4-quinolinyl]carbamate (for a preparation see Intermediate 52) (333 mg, 0.80 mmol), 1,1-dimethylethyl[2-(4-iodo-1H-imidazol-1-yl)ethyl]carbamate (for a preparation see Intermediate 80) (270 mg, 0.8 mmol), potassium carbonate (443 mg, 3.2 mmol) and tetrakis(triphenylphosphine)palladium(0) (46 mg, 0.040 mmol) in toluene (10 ml) and ethanol (10 ml) was refluxed under nitrogen for 16 h then cooled to room temperature and the insoluble were filtered off. Potassium carbonate (443 mg, 3.2 mmol) and tetrakis(triphenylphosphine)palladium(0) (46 mg, 0.040 mmol) were added to the filtrate and the resulting mixture refluxed for 7 h then cooled to room temperature and the insoluble filtered off. The resulting solution was concentrated in vacuo. Purification of the residue by flash chromatography on silica gel (gradient: 0 to 6% MeOH in DCM) gave 1-methylethyl((2S,4R)-1-acetyl-6-{1-[2-({[(1,1-dimethylethyl)oxy]carbonyl}amino)ethyl]-1H-imidazol-4-yl}-2-methyl-1,2,3,4-tetrahydro-4-quinolinyl)carbamate (47 mg, 0.094 mmol, 12%) as a light brown solid.
