anilines. The reaction of the indicated aminonitrile with 4-chlorobutanoyl chloride and subsequent cyclization of the intermediate amide gave rise to 2-(3-chloropropyl)-3H-spiro[benzo[h]quinazoline-5,1′-cycloheptane]-4(6H)-one, which in the presence of potassium hydroxide underwent cyclization to form 10,11-dihydro-5H-spiro[benzo[h]pyrrolo[2,1-b]quinazolin-6,1′-cycloheptane]-7(9H)-one. The reaction of the
