实验步骤: 2-(4-Chloro-phenyl)-4H-furo[3,2-b]pyrrole-5-carboxylic acid ethyl ester (29 mg, 0.1 mmol) was prepared as described hereinabove (see, preparation of Compound 4), and placed in a heavy-walled glass tube with a threaded Teflon plug. 1-Isothiocyanato-3-methoxy-propane (131 mg, 1. mmol, 10 molequivalents) and triethylamine (202 mg, 2 mmol, 20 molequivalents) were added thereto, the tube was sealed and the mixture was heated while stirring at 120° C. for 6 hours. The mixture was then cooled to room temperature, dissolved in chloroform and the solvents were evaporated under reduced pressure. The crude residue was dissolved in dichloromethane and was purified by column chromatography using a 95:5 hexane:ethyl acetate mixture as eluent, to give Compound 28 (13 mg, 35% yield) as an orange solid. the tube was sealed the mixture was heated The mixture was then cooled to room temperature the solvents were evaporated under reduced pressure The crude residue was dissolved in dichloromethane was purified by column chromatography
