实验步骤: 1-[(4-Chlorophenyl)thio)-2-propanone (50 g, 0.25 mol) was added to polyphosphoric acid (300 g) and the mixture was stirred as the temperature was gradually raised to 120° C. as an exotherm started. The mixture was stirred at 130° C. for 1 hour, diluted with water, extracted with ethyl ether and the organic phase was dried and concentrated. The residue was stirred in methanol (200 ml), filtered and the filtrate concentrated to give 17.5 g (40%) of 5-chloro-3-methylbenzo(b)thiophene: bp 120° C. (0.6 mm Hg). The mixture was stirred at 130° C. for 1 hour extracted with ethyl ether the organic phase was dried concentrated The residue was stirred in methanol (200 ml) filtered the filtrate concentrated

反应条件: temp:25.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: Chloroacetone (32.3 g, 0.347 mol) was added to a mixture of 4-chlorothiophenol (50 g, 0.347 mmol) and sodium hydroxide (14 g, 0.347 mol) in water (400 ml) and the mixture was stirred at 25° C. for 1 hour. The mixture was extracted with ethyl ether and the organic phase was washed with water, dried with magnesium sulfate and concentrated to give 69 g (99%) of 1-[(4-chlorophenyl)thio]-2-propanone. The mixture was extracted with ethyl ether the organic phase was washed with water dried with magnesium sulfate concentrated
