Procedure
9.3 parts by weight of 3-amino-4-methoxycarbonyl-1,5-dihydrothiophene hydrochloride, 6.0 parts by weight of triethylamine, 7.4 parts by weight of cyclohexyl isocyanate and 30 parts by weight of acetonitrile were combined, and the mixture was stirred for 3 hours at 25° C. and then evaporated down. The residue was washed with water and recrystallized from toluene. 4.5 parts by weight of N-cyclohexyl-N'-(3-methoxycarbonyl-2,5-dihydrothien-4-yl)-urea of melting point 153°-154° C. were obtained.
