Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps, and cheap raw materials. 2550-36-9, name is (Bromomethyl)cyclohexane, A new synthetic method of this compound is introduced below., Recommanded Product: (Bromomethyl)cyclohexane
After 500 mg of hydroxyphthalimide (Aldrich) was dissolved in 5 ml of dimethylformamide under argon flow, 0.47 ml of (bromomethyl)cyclohexane (Aldrich) was added, and 0.5 ml of 1,8-diazabicyclo[5.4.0]undec-7-ene (Aldrich) was slowly added. After the mixture was stirred at 60 C. for 2 hours, the temperature was again lowered to room temperature, and then the reaction was stopped by adding a 2 N hydrochloric acid solution. The reaction liquid was diluted by adding 20 ml of ethyl acetate, followed by drying over magnesium sulfate and then filtration. The filtrate was concentrated under reduced pressure, and the residue was subjected to silica gel column chromatography using a mixed eluent of ethyl acetate/hexane (1:5) and then dried to obtain 787 mg of a compound (yield: 99%). 400 mg of the obtained compound was dissolved in 5 ml of dichloromethane, and 0.14 ml of methyl hydrazine (TCI) was slowly added at 0 C. After the reaction liquid was stirred at room temperature for 2 hours, the temperature was again lowered to 0 C. The generated solid was then filtered out, and 1 ml of a 4 M-hydrochloric acid dioxane solution (Aldrich) was added to the residual filtrate, followed by filtration and drying, to obtain 240 mg of a solid (yield: 94%). 21 mg of the obtained solid and 50 mg of SAC-0906 obtained as obtained above were dissolved in 1 ml of pyridine (Aldrich) under argon flow, followed by stirring at 80 C. for 4 hours. After the temperature was lowered to room temperature, the reaction liquid was acidified by adding a 2 N hydrochloric acid solution, followed by extraction with 20 ml of diethyl ether, drying over magnesium sulfate, and filtering. The filtrate was concentrated under reduced pressure, and the residue was subjected to silica gel column chromatography using a mixed eluent of ethyl acetate/hexane (1:5) to obtain the target compound SAC-1103 (50 mg, yield: 82%). 1H-NMR (400 MHz, CDCl3) delta 5.87-5.78 (m, 2H), 5.35-5.34 (m, 1H), 5.29-5.26 (m, 1H), 5.16 (m, 1H), 4.24-4.14 (m, 3H), 3.86-3.76 (m, 2H), 3.58-3.51 (m, 1H), 2.41-0.61 (m, 46H)
The synthetic route of 2550-36-9 has been constantly updated, and we look forward to future research findings.
