To a stirring solution of 0.69 g (1.5 mmol) of 8-chlorodibenz[b,f][1,4]oxazepine-10(11H)-carboxylic acid, 2-[3-[(2-furanylmethyl)thio]-1-oxopropyl]hydrazide (13), prepared as described above in Example 13, in 5 mL of HOAc was added 0.13 mL (1.5 mmol) of a 30% hydrogen peroxide solution. After one hour, the reaction mixture was lyophilized. The product was recrystallized from EtOAc-hexanes. The yield of 8-chlorodibenz[b,f][1,4]oxazepine-10(11H)-carboxylic acid, 2-[3-[(2-furanylmethyl)sulfinyl]-1-oxopropyl]hydrazide (60) was 0.56 g (79%). Analysis calculated for C22H20N3O5SCl (M.W. 473.93): C, 55.76; H, 4.25; N, 8.87; Cl, 7.48; S, 6.77. Found: C, 55.67; H, 4.30; N, 8.79; Cl, 7.47; S, 6.56.
