Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: By the reaction of 2,3,4,5-tetrahydro-3-(1-pyrrolidinylcarbonyl)-1H-3-benzazepin-7-sulfonamide and 3-cyclohexen-1-ylisocyanate in a manner analogous to that described in Example 1, there is obtained 1-(3-cyclohexen-1-yl)-3-{[2,3,4,5-tetrahydro-3-(1-pyrrolidinylcarbonyl)-1H-3-benzazepin-7-yl]sulfonyl}urea, m.p. 211°-212° C.
