实验步骤: 4-(1-Methylpyrrol-2-ylmethyl)nitrobenzene (1.2 g, 5.5 mmol) [prepared as in Example 7, Step (b)], 2,4-dimethylbenzoyl chloride (1.6 g, 9.5 mmol), and triethylamine (1.3 ml, 9.3 mmol) were dissolved in xylenes (50 ml), and the reaction mixture was heated at reflux under argon. After 48 h, the reaction mixture was passed through a Florisil® column (hexane followed by hexane-ethyl acetate, 95:5) to give 4-{5-(2,4-dimethylbenzoyl)-1-methyl-1H-pyrrol-2-yl-methyl}nitrobenzene (0.81 g, 42%) as a solid. ##STR41## the reaction mixture was heated at reflux under argon

实验步骤: As described in Example 9, 0.471 g (1.5 mmol) of 5-(4-aminobenzoyl)-6,11-dihydro-5H-dibenz[b,e]azepine is reacted with 0.303 g (1.8 mmol) of 2,4-dimethylbenzoyl chloride in 10 ml of dichloromethane. The product is recrystallized from hexane-dichloromethane to give 0.38 g of crystals, m.p. 197-199° C. The product is recrystallized from hexane-dichloromethane

实验步骤: 33.7 g (0.2 mol) of 2,4-dimethylbenzoyl chloride were warmed to 80° C. under a nitrogen atmosphere. 46 g (0.2 mol) of 6-methoxy-(6H)-dibenz[c,e][1,2]oxaphosphorin were added dropwise with stirring. The batch began to crystallize even during the addition. The temperature when then slowly increased to 135° C. with the proviso that toluene was added as diluent at 90° C. After digestion with toluene, 58 g (83% of theory) of the abovementioned compound of melting point 166° C. were obtained from the crystallizate. to crystallize even during the addition was added as diluent at 90° C After digestion with toluene, 58 g (83% of theory) of the abovementioned compound of melting point 166° C. were obtained from the crystallizate

实验步骤: To a suspension of anhydrous aluminum chloride (16.2 g) dispersed in 1,2-dichlorobenzene (150 ml) was added fluorobenzene (13 g), and thereto was added dropwise 2,4-dimethylbenzoyl chloride (17.0 g) at 0-20° C. The mixture was stirred at 10-30° C. for 1 hr and heated to 80° C. The mixture was stirred for 1 hr, cooled again and poured into 6N hydrochloric acid. The reaction mixture was diluted with a great excess toluene and partitioned. The obtained organic layer was washed successively with 5% aqueous sodium hydroxide solution and water, and the solvent was evaporated under reduced pressure. The residue was purified by silica gel column chromatography using cyclohexane-ethyl acetate as eluent to give nearly pure 1,3-dimethyl-4-(4′-fluorobenzoyl)benzene (19.4 g, 85%) as pale-yellow oil. The spectrum data of this oil were the same as those confirmed in Example 7. heated to 80° C The mixture was stirred for 1 hr cooled again partitioned The obtained organic layer was washed successively with 5% aqueous sodium hydroxide solution and water the solvent was evaporated under reduced pressure The residue was purified by silica gel column chromatography
