In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles, 1-Bromo-3,5-dimethyladamantane, other downstream synthetic routes, hurry up and to see.

Adding a certain compound to certain chemical reactions, such as: 941-37-7, name is 1-Bromo-3,5-dimethyladamantane, belongs to bromides-buliding-blocks compound, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound 941-37-7, 941-37-7

To a solution of l-Bromo-3,5-dimethyl adamantane (100 gm) in acetonitrile (370 ml), sulphuric acid (760 ml) was added slowly at a temperature of 10-150C over 4hrs under nitrogen atmosphere. Temperature of the reaction mass was slowly raised over 2 hrs and maintained at 20-250C for 12 hrs under nitrogen purging. Nitrogen purging was continued for further 4 hrs. Reaction mass was transferred into a mixture of toluene (1000 ml) and ice (3.0 Kg) at temperature below 100C. Temperature of reaction mass was raised, maintained for 30 min at 25 -3O0C and allowed to settle for 15 min. Layers were separated and the aqueous layer was extracted with toluene (1800 ml), dried over sodium sulfate, treated with activated carbon (5 gm) and filtered. Clear filtrate was collected and toluene was distilled off under vacuum below 5O0C. The obtained residue was dissolved in ethanol (80 ml) and p-toluene sulfonic acid (90.8 gm) was added in 4 lots at temperature of 25-35C over 30 min. Reaction mass was maintained for 60 min and diisopropyl ether (240 ml) was added over 30 min. Reaction mixture was maintained at 25-35C for 30 min, cooled and maintained at 0-5C for 1 hr. Product was filtered, wet cake was washed with chilled diisopropyl ether. (50 ml) and dried at a temperature of 45-500C for 4 hrs. The dried product (100 gm) was dissolved in methylene chloride (150 ml) and acetone (300 ml) was added slowly over 30 min. Reaction mixture was maintained at 25 – 3O0C for 30 min. Cooled the mass to 10-150C and maintained for 60 min. The precipitated product was filtered, wet cake was washed with chilled acetone (50 ml) and dried at 45-5O0C. Yield: 51.2%.
