YieldReaction ConditionsOperation in experiment
With triethylamine; In dichloromethane; at 5 - 20℃; for 20h; The solution of 3-dimethylaminophenyl isocyanate in 0.14 N tetrahydrofuran can be prepared in the following way: 1.46 g (7 mmol) of N1,N1-dimethylbenzene-1,3-diamine dihydrochloride, followed by 9.9 cm3 (71.64 mmol) of triethylamine, are added, at a temperature in the region of 5 C., under an argon atmosphere, to 2.82 g (9.5 mmol) of triphosgene in solution in 150 cm3 of dichloromethane. After stirring for 20 hours at a temperature in the region of 20 C., the reaction mixture is concentrated to dryness under reduced pressure (2.7 kPa), to give a residue which is triturated in 50 cm3 of tetrahydrofuran. After filtration, a solution of 3-dimethylaminophenyl isocyanate in approximately 0.14 N tetrahydrofuran is obtained, which solution is used directly in the subsequent step.

YieldReaction ConditionsOperation in experiment
With sodium hydrogencarbonate; In water; ethyl acetate; Commercially available N,N-dimethyl-1,3-phenylene diamine dihydrochloride salt (12 g) was neutralized with solid NaHCO3 (partitioned between H2O and EtOAc). After neutralization, the phases were separated and the organic phase dried and concentrated to give a brownish oil (7.8 g, 57.3 mmol) which was used as is in the next step. Dimethyl acetylene dicarboxylate 15 (7.044 mL, 57.3 mmol) was dissolved in MeOH and treated with the neutralized aniline 16 (portionwise) in MeOH at 0 C. Considerable heat was generated (exothermic reaction). The mixture (brown) was heated at 65 C. for 2 hours. The brown solution was concentrated to dryness, extracted into EtOAc and washed with sat. NaHCO3 (aq), followed by brine, dried (MgSO4), filtered, and concentrated. The crude mixture was purified by flash chromatography using a 10% EtOAc/hexane solvent to afford 12 g of compound 17.

With pyridine; Example 242 4-(3-Dimethylamino-phenylamino)-5,8-dimethoxy-quinoline-3-carbonitrile A mixture of 0.148 g of 4-chloro-5,8-dimethoxy-3-quinolinecarbonitrile, 0.146 g of <strong>[3575-32-4]N,N-dimethyl-1,3-phenylenediamine dihydrochloride</strong>, 0.2 ml of pyridine, and 5 ml of ethoxyethanol was stirred under nitrogen, at reflux temperature for 30 minutes. Then the mixture was partitioned between ethyl acetate and saturated sodium chloride solution. The organic layer was dried and concentrated in vacuo. The residue thus obtained was chromatographed on silica gel eluding with ethyl acetate. Solvent was removed from product fractions giving 0.160 g of 4-(3-dimethylamino-phenylamino)-5,8-dimethoxy-quinoline-3-carbonitrile as a solid, mp 103-105C; mass spectrum (EI, m/e): M 348.1588.

YieldReaction ConditionsOperation in experiment
With toluene-4-sulfonic acid; triethylamine; In ethanol; dichloromethane; EXAMPLE 1 Preparation of 1-(3-Dimethylaminophenyl)-2-methyl-5-phenyl-1H-pyrrole-3-carboxylic acid ethyl ester <strong>[3575-32-4]N,N-dimethyl-1,3-phenylenediamine dihydrochloride</strong> (5 mmol, 1.09), triethylamine (10 mmol, 1.4 mL), 3-oxo-2-(2-oxo-2-phenyl-ethyl)-butyric acid ethyl ester (5 mmol, 1.2 g), and tosic acid (0.1 g) were combined in ethanol (25 mL), then heated under reflux (12 hrs). The solvents were removed under vacuum, the resulting oil was redissolved in methylene chloride, then applied to a silica column. The purified product was collected as a translucent oil. The named compound was identified by 1H-NMR (CDCl3, ppm) 1.28 t (3H), 2.35 s (3H), 2.77 s (6H), 4.2 q (2H), 6.3-6.7 m (4H), and 7.0-7.3 m (5H).

YieldReaction ConditionsOperation in experiment
With toluene-4-sulfonic acid; triethylamine; In ethanol; dichloromethane; EXAMPLE 13 Preparation of 1-(3-Dimethylaminophenyl)-5-methyl-2-phenyl-1H-pyrrole-3-carboxylic acid ethyl ester N,N-Dimethyl-1,3-phenylenediamine dihydrochloride (5 mmol, 1.0 g), 2-benzoyl-4-oxo-pentanoic acid ethyl ester (5 mmol, 1.2 g), triethylamine (10 mmol, 10 g), and tosic acid (0.1 g) were combined in ethanol, then heated under reflux. The resulting oil was resuspended in methylene chloride, then washed with water, 5% sodium bicarbonate, and brine. The organic layer was dried over NaSO4, then the solids were separated and the solvents removed under vacuum. The crude material was purified over silica gel and yielded the named product (m.p. 111.7 C.-114 C.).
