Conditions

Temperature: 110 °C

Procedure

A mixture of 335 mg of 2,6-dichlorobenzoyl chloride and 258 mg of N,N-diisopropylethylamine is stirred in 2 ml of xylene while 314 mg of 5-(4-amino-benzoyl)-6,11-dihydro-5H-dibenz[b,e]azepine is added. The reactants are refluxed in an oil bath at 110° C. for 18 hours. The xylene is evaporated in vacuo to a residue which is partitioned between methylene chloride and water. The organic layer is separated, washed with 1N HCl, 1 M NaHCO3, and brine. The organic layer is dried with Na2SO4 and passed through a pad of hydrous magnesium silicate. Hexane is added to the filtrate at the boil to give 370 mg of the desired product as a crystalline solid, m.p. 257°-259 ° C.
