Procedure: As described for Example 136, a mixture of 0.349 g of 2-chloro-5-(4-aminobenzoyl)-6,11-dihydro-5H-dibenz[b,e]azepine, 0.131 g of triethylamine and 0.219 g of 2,3-dimethylbenzoyl chloride in 13 ml of dichloromethane is stirred at room temperature for 18 hours. Work-up gives a solid which is recrystallized from dichloromethane-hexane to give 0.38 g of crystals 191°-193° C. Work-up gives a solid which is recrystallized from dichloromethane-hexane

Procedure: As described for Example 9, 0.628 g (2 mmol) of 5-(4-aminobenzoyl)-6,11-dihydro-5H-dibenz[b,e]azepine is reacted with 0.506 g (3.0 mmol) of 2,3-dimethylbenzoyl chloride in dichloromethane. The product is recrystallized from hexane-dichloromethane to give 0.12 g of crystals, m.p. 138°-142° C. The product is recrystallized from hexane-dichloromethane

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: T-butylcarbazate (35.15 g, 266 mmol) and 200 mL of CH2Cl2 were added to a round bottom flask. Potassium carbonate (55.2 g, 0.4 moles) dissolved in 350 mL of water was added to the flask, and the mixture was stirred for 15 minutes with ice chilling. 2,3 dimethylbenzoyl chloride (44.9 g, 266 mmol) in ca. 200 mL of CH2Cl2 was added drop-wise from a 500 mL separatory funnel over 30 minutes. The reaction was allowed to stir overnight and then the reaction mixture was poured into a 1 L separatory funnel and the CH2Cl2 phase was separated. Then ca. 150 mL of water was added, and the mixture was extracted twice with 150 mL of CHCl3. The combined organic phase was back-extracted with 100 mL of water, then with 1N HCl (250 mL), to remove the hydrazide. The organic phase was dried, stirred with charcoal, and the solvent removed in vacuo to yield a light tan solid (71.5 g) of N′-(2,3-dimethyl-benzoyl)-hydrazinecarboxylic acid, tert-butyl ester. 1H NMR (300 MHz, CHCl3) δ (ppm): 7.7 (br, 1H), 7.22 (m, 2H), 7.1 (t, 1H), 7.85 (br, 1H), 2.35 (s, 3H), 2.3 (s, 3H), 1.5 (s, 9H). was added to the flask to stir overnight the reaction mixture was poured into a 1 L separatory funnel the CH2Cl2 phase was separated Then ca. 150 mL of water was added the mixture was extracted twice with 150 mL of CHCl3 The combined organic phase was back-extracted with 100 mL of water with 1N HCl (250 mL), to remove the hydrazide The organic phase was dried stirred with charcoal the solvent removed in vacuo
