Procedure
Reflux a mixture of 200 mg of dibenzo[b,f]thiepin-3-carboxaldehyde-5,5-dioxide (0.74 mmole) and 82 mg of n-butylamine (1.11 mmole) in 0.30 ml of benzene, with azetropic removal of water, for 45 minutes. Evaporate the mixture to remove the benzene and excess butylamine and obtain the title product as an oil.
