Reaction Steps

8-chlorodibenz[b,f][1,4]oxazepine-10(11H)-carboxylic acid, 2-[3-[(2-furanylmethyl)amino]-1-oxopropyl]hydrazide (25) was prepared in the same manner as 8-chlorodibenz-[b,f][1,4]-oxazepine-10(11H)-carboxylic acid, 2-[1-oxo-3-[(2-thienylmethyl)amino]propylhydrazide, monohydrochloride (18), as described above in Example 18, on a 0.37 mmol scale from 8-chlorodibenz[b,f][1,4]oxazepine-10(11H)-carboxylic acid, 2-[3-[[(1,1-dimethylethoxy)carbonyl](2-furanylmethyl)amino]-1-oxopropyl]hydrazide (24), prepared as described above in Example 24, to yield 0.14 g (78%) of product. Analysis calculated for C22H21N4O4Cl.HCl. 0.25 H2O (M.W. 481.86): C, 54.84; H, 4.71; N, 11.63. Found: C, 54.56; H, 4.60; N, 11.33.
