YieldReaction ConditionsOperation in experiment
94% With 1,3-dibromo-5,5-dimethylimidazolidine-2,4-dione; In dichloromethane; at 0 - 20℃; for 1.66667h;Product distribution / selectivity; Example 10b. Alternative synthetic route to (S)-1-(3-((1 S)-5-(2-(1 H-tetrazol-5- yl)phenyl)-2l3-dihydro-1H-inden-1-yl)-2-ethyl-7-methyl-3H-imida20[4,5-b]pyridin-5-yl)-2- methylpropan-1-ol; Step 1. 6-Bromo-2-chloro-4-methyl-pyridin-3-ylamine [6-bromo-<strong>[133627-45-9]2-chloro-4-methylpyridin-3-amine</strong>]; <strong>[133627-45-9]3-Amino-2-chloro-4-methylpyridine</strong> (50.0 g, 351 mmol) was dissolved in dichloromethane (500 mL) under nitrogen and the solution cooled in an ice bath to between 0-1 0C. Dibromo-5,5-dimethylhydantoin (51.1 g, 179 mmol) was added in 5 portions over 40 min. After the addition was finished, the mixture was stirred at room temperature for 2 hours. The reaction mixture was passed through a short pad of silica gel, eluted with 30% ether/ dichloromethane (1 L). The mixture was concentrated and heptane was added. The precipitate was collected by filtration, washed with heptane, and air dried to give 6-bromo-2-chloro-4-methyl-pyridin-3-ylamine (73.3 g, 94%). MS: 223.0 (APCI)+; 220.9 (APCI)"; Example 10c. (S)-1-(3-((1S)-5-(2-(1H-tetrazol-5-yl)phenyl)-2,3-dihydro-1H-inden-1-yl)-2- ethyl-7-methyl-3H-imidazo[4,5-b]pyridin-5-yl)-2-methylpropan-1-ol; Step 1 Bromo-2-chloro-4-methyl-pyridin-3-ylamine; 3-Amino-2-chloro-4-methy.pyridine (50.0 g, 351 mmol) was dissolved in DCM (500 mL) under nitrogen and cooled the solution in an ice bath to between 0-1 0C. <n="82"/>Dibromo-5,5-dimethylhydantoin (51.1 g, 179 mmol) was added in 5 portions over 40 min. After the addition was finished, the mixture was stirred at room temperature for 2 hours. The reaction mixture was passed through a short pad of silica gel, eluted with 30% ether/DCM (1 L). The mixture was concentrated and heptane was added. The precipitate was collected by filtration, washed with heptane, and air dried to give 6- Bromo-2-chloro-4-methyl-pyridin-3-ylamine (73.3 g, 94%).
