Participants

Reaction Steps

To a mixture of 3-chloro-5-methoxybenzenethiol (2.1 g) and DMF (dry) (30 mL) were added methyl 4-chloroacetoacetate (1.407 mL) and K2CO3 (1.994 g) at 0° C., and the mixture was stirred at room temperature for 5 h. The mixture was poured into water at room temperature and extracted with EtOAc. The organic layer was separated, washed successively with water and brine, dried over MgSO4 and concentrated in vacuo. The residue was purified by silica gel column chromatography (EtOAc/hexane) to give the title compound (1.440 g).
