Reaction Steps
A sample of 6,7-dihydrobenzo[b]thiophene is stirred with silver isocyanate and iodine as described in Example 39 and the resulting product, 5-iodo-4,5,6,7-tetrahydrobenzo[b]thien-4-yl isocyanate is treated with concentrated ammonia solution to afford 5-iodo-4,5,6,7-tetrahydrobenzo[b]thien-4-ylurea. This latter product is then reduced in the manner described in Example 40 to afford 4,5,6,7-tetrahydrobenzo[b]thien-4-ylurea.
