Reaction Steps
8-chlorodibenz[b,f][1,4]oxazepine-10(11H)-carboxylic acid, 2-[1-oxo-4-(3-thienyl)-3E-butenyl]hydrazide (trans) (30) and 8-chlorodibenz[b,f][1,4]oxazepine-10(11H)-carboxylic acid, 2-[1-oxo-4-(3-thienyl)-3Z-butenyl]hydrazide (cis) (31) were prepared in the manner described in Example 7 on a 5.2 mmol scale from 4-(3-thienyl)-3-butenoic acid (29), prepared as described above in Example 29, and 8-chlorodibenz[b,f][1,4]oxazepine-10(11H)-carboxylic acid, hydrazide (1), prepared as described above in Example 1, to yield 33% trans and 14% cis products after separation by column chromatography.
