実験手順

A flask was charged with 1-methylethyl[(2S,4R)-1-acetyl-6-ethynyl-2-methyl-1,2,3,4-tetrahydro-4-quinolinyl]carbamate (for a preparation, see Intermediate 58) (80 mg, 0.254 mmol) and copper(I) iodide (2.423 mg, 0.013 mmol) then filled with N,N-dimethylformamide (DMF) (1.8 mL) and methanol (0.200 mL). 1,1-Dimethylethyl (2-azidoethyl)carbamate (for a preparation, see Intermediate 78) (95 mg, 0.509 mmol) was added and the resulting mixture was stirred under microwave irradiation at 100° C. for 2 h then cooled to room temperature. The reaction mixture was partitioned between EtOAc and brine and the layers were separated. The aqueous phase was extracted with EtOAc (3×) and the combined organic phases were washed with brine, dried over a Na2SO4 cartridge and concentrated in vacuo. Purification of the residue on SP4 using a 10 G silica cartridge (gradient: 5 to 25% (10% MeOH in DCM) in DCM) gave 1-methylethyl((2S,4R)-1-acetyl-6-{1-[2-({[(1,1-dimethylethyl)oxy]carbonyl}amino)ethyl]-1H-1,2,3-triazol-4-yl}-2-methyl-1,2,3,4-tetrahydro-4-quinolinyl)carbamate (108 mg, 0.216 mmol, 85% yield) as a pale yellow foam. LCMS (method A): Retention time 0.95 min, [M+H]+=501.26
