Versuchsvorschrift
In a similar manner, as described in Example 1, 4,5,6,7-tetrahydrobenzo[b]thiophen-4-amine hydrochloride is allowed to react with cyclohexyl isocyanate in dry tetrahydrofuran to afford 7 grams of 1-cyclohexyl-3-(4,5,6,7-tetrahydrobenzo[b]thien-4-yl)urea, melting point 222° C. to 225° C.
