반응 단계

To a suspension of aluminum trichloride (2.75 g, 20.6 mmol) and methyl 2-chloro-2-oxoacetate (1.90 mL, 20.7 mmol) in dry DCM (25 mL), cooled at 0° C. and under nitrogen atmosphere, is added 2-methylthiophene (1.00 mL, 10.33 mmol) dropwise. The reaction is stirred at RT for 15 hours. Then the mixture is cooled at 0° C., ice-water is slowly added and the organic phase is washed with aq. NaHCO3 and brine, dried over Na2SO4 and evaporated to obtain intermediate I266 as a brown oil (1.9 g, quantitative yield).
