Reaction Steps

Dissolve 1.0 gm of 9-chlorocarbonyl-6,11-dihydro-11-oxo-dibenz[b,e]oxepin as prepared in Example 10, Step A, in 10 cc of anhydrous tetrahydrofuran with stirring and add 2 ml of N,N-dimethylethanolamine. Stir at room temperature for 18 hours and strip the mixture to dryness. Partition the residue between ether and dilute hydrochloric acid and separate the aqueous layer. Basify the aqueous layer with aqueous ammonia and extract with ethyl acetate.
