Application of 4415-82-1, 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. 4415-82-1, name is Cyclobutylmethanol. A new synthetic method of this compound is introduced below.
To a mixture of 1.05 g (26.25 mmol; 60% purity) of sodium hydride in 15 ml of DMF were added 1.33 g (15.44 mmol) of cyclobutylmethanol and the mixture was stirred at RT for 1 h. Subsequently, a mixture of 1.0 g (7.72 mmol) of 3-chloropyrazin-2-amine in 10 ml DMF was added thereto and the reaction mixture was heated to 100 C. After 20 h, water was added to the mixture, which was extracted repeatedly with ethyl acetate. The combined organic phases were washed with saturated sodium chloride solution, dried over sodium sulphate, filtered and concentrated by evaporation. The residue obtained was purified by means of silica gel chromatography (eluent: cyclohexane/ethyl acetate gradient). 1.25 g of the title compound were obtained (89% of theory; 98% purity). (1270) LC-MS (Method 2): Rt=0.80 min (1271) MS (ESpos): m/z=180 (M+H)+
At the same time, in my other blogs, there are other synthetic methods of this type of compound,4415-82-1, Cyclobutylmethanol, and friends who are interested can also refer to it.
