HCID 203489501-Methoxy-1-methyl-3-(4,5,6,7-tetrahydrobenzo[b]thien-4-yl)urea

Procedure

Following the procedure described in Example 6, N,O-dimethyl hydroxylamine hydrochloride and 4,5,6,7-tetrahydrobenzo[b]thien-4-yl isocyanate are allowed to react to give 1-methoxy-1-methyl-3-(4,5,6,7-tetrahydrobenzo[b]thien-4-yl)urea, which is crystallized from acetone-hexane-ether to give product melting at 60° C. to 62.5° C.
