58% | With potassium carbonate; In N,N-dimethyl-formamide; at 0 - 20℃; for 4.0h; | To a solution of <strong>[127675-46-1]3-chloro-2,4-difluorobenzaldehyde</strong> (2.0 g, 11 mmol) and potassium carbonate (2.4 g, 17 mmol) in N,N-dimethylformamide (20 mL) at 0 C was added dropwise methyl 2-mercaptoacetate (1.4 g, 14 mmol). The mixture was stirred at room temperature for 4 hours, then diluted with water (30 mL) and extracted with ethyl acetate (2 x 50 mL). The organic layer was concentrated in vacuo, and the residue was purified by silica gel chromatography [petroleum ether: ethyl acetate = 20: 1] to give compound B-194 (1.6 g, 58% yield) as a yellow solid. LCMS (B): tR=0.912 min., (ES+) m/z (M+H)+ =245.0. |
