2566-44-1, The major producers of chemicals have been the Europe, Japan and China. Due to the growing call for a cleaner, greener environment, people will have to find innovative ways to maintain their relevance. Here is a compound 2566-44-1, name is 2-Cyclopropylethanol. This compound has unique chemical properties. The synthetic route is as follows.
Synthesis of 3-((1R,5S,9r)-3-(2-cyclopropylethyl)-9-methoxy-3-azabicyclo[3.3.1]nonan-9-yl)benzamide hydrochloride To a solution of 2-cyclopropylethanol (0.21 g, 2.41 mmol) in dichloromethane (40 mL) was added silica (3 g), followed by pyridinium chlorochromate (0.52 g, 2.41 mmol). After 2 h of stirring the reaction mixture was filtered through a plug of silica and the desired aldehyde eluted with dichloromethane. The collected dichloromethane solution was concentrated to 30 mL and 3-((1R,5S,9r)-9-methoxy-3-azabicyclo[3.3.1]nonan-9-yl)benzamide hydrochloride (0.25 g, 0.80 mmol) added. To the resulting suspension was then added triethylamine (0.33 mL, 2.41 mmol) and sodium triacetoxyborohydride (0.51 g, 2.41 mmol) and the reaction mixture stirred for 3 hours. Concentrated aqueous ammonia was added and the mixture was extracted with dichloromethane (*3). The combined organic phases were concentrated and purified by reverse phase chromatography (C18) to give 3-((1R,5S,9r)-3-(2-cyclopropylethyl)-9-methoxy-3-azabicyclo[3.3.1]nonan-9-yl)benzamide (0.17 g, 62% yield). 2.0 M HCl in diethyl ether (0.25 mL, 0.50 mmol) was added to a solution of 3-((1R,5S,9r)-3-(2-cyclopropylethyl)-9-methoxy-3-azabicyclo[3.3.1]nonan-9-yl)benzamide (0.17 g, 0.50 mmol) in dichloromethane (5 mL) and then the volatiles removed. The residue was freeze-dried from water to give 3-((1R,5S,9r)-3-(2-cyclopropylethyl)-9-methoxy-3-azabicyclo[3.3.1]nonan-9-yl)benzamide hydrochloride (0.10 g, 55%)
While traditionally a conservative industry, chemical producers will need to modernize their PR strategies to stay relevant.we look forward to future research findings about 2566-44-1, 2-Cyclopropylethanol.
