YieldReaction ConditionsOperation in experiment
With hydrogen;palladium 10% on activated carbon; In methanol; at 20℃; Example 1 : Chemical synthesis of compound 1 D; Nitrophloroglucinol (1 g, 6.5 mMol) was dissolved in 10 ml of methanol and hydrogenated in a hydrogen atmosphere in the presence of 0.1 g of 10percent Pd/C overnight at room temperature. The solvent was removed by evaporation an the residue was dissoved in 12 ml of dimethylformamide. 2-chlor-5-nitrobenzoic acid (1.2 g; 6 mMol), 1.7 g of K2CO3, 0.18 g of copper powder and 0.18 g of CuCI were added and the mixture was refluxed for 3 hours. After cooling to room temperature, 12 ml of concentrated HCI and 120 ml of water were added, and the product was extracted with 120 of ethylacetate. The organic phase was dried over Na2SO4 and evaporated. The product was dissolved in 12 ml of methanol; 0.1 g of palladium (10percent ob charcoal) was added and hydrogenated in a hydrogen atmosphere overnight at room temperature. The catalyst was removed by centrifugation, and the solvant was evaporated to obtain compound 1 D.
With hydrogen;palladium 10% on activated carbon; In methanol; at 20℃; Example 4: Chemical synthesis of compounds 89, 93, and 96Nitrophloroglucinol (1 g, 6.5 mMol) was dissolved in 10 ml of methanol and hydrogenated in a hydrogen atmosphere in the presence of 0.1 g of 10percent Pd/C overnight at room temperature. The solvent was removed by evaporation and the residue was dissoved in 12 ml of dimethylformamide. 2-chlor-5-nitrobenzoic acid (1.2 g; 6 mMol), 1.7 g of K2CO3, 0.18 g of copper powder and 0.18 g of CuCI were added and the mixture was refluxed for 3 hours. After cooling to room temperature, 12 ml of concentrated HCI and 120 ml of water were added, and the product was extracted with 120 of ethylacetate. The organic phase was dried over Na2SO4 and evaporated. The product was dissolved in 12 ml of methanol, 0.1 g of palladium (10percent ob charcoal) was added and hydrogenated in an H2-atmosphere overnight at room temperature. The catalyst was removed by centrifugation, and the solvant was evaporated to obtain compound 89.Compound 89 (2 mMol ) was dissolved in 3 ml of methanol at 00C and 0.6 ml of 10 M NaOH and 0.5 mul of fluorbenzoylchlohd (4.2 mMol) was added. After 2.5 hours another portion of 1 ml of 10 M NaOH was added. After 30 min at room temperature, the mixture was acidified with concentrated hydrochloric acid, diluted with 30 ml of water and extracted with 20 ml of ethylacetate. The organic layer was dried and evaporated to obtain compound 93.For reductive amination, compound 89 (1.33 mMol) was dissolved in 2 ml of methanol and 200 mul of cinnamon aldehyde (1.5 mMol) was added. NaBH4 was added in 0.5 mM portions (19 mg each) every 3 hours, until the reaction was complete. The mixture was diluted with water, acidified and extracted with ether. The ether phase was dried, evaporated and compound 96 was obtained.
