 [(3-cyano-5-phenyl -1H- pyrrol-2-yl) thio] acetic acid




 (2-phenyl-2-oxoethyl) malononitrile (1. 0g, 54. 3mmol), methanol (150ml) and thioglycolic acid (6. 0g, 52. 6_〇1) loading into the reactor, and the mixture was heated at reflux for 0.5 hours. Let the mixture was cooled and stirred for 0.5 hours at room temperature and was stirred under ice-cooling 0.5 hours. The crystals were collected by filtration. With ethyl acetate (60ml) washing the wet crystals and reduced pressure, 50 ° C and dried to give the title compound (8. 8g, yield 60%).
