558-42-9, Adding a certain compound to certain chemical reactions, such as: 558-42-9, 1-Chloro-2-methyl-2-propanol, 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, 558-42-9, blongs to alcohols-buliding-blocks compound.
Example 7A 1-Chloro-2-methylpropan-2-yl {4,6-diamino-2-[1-(2-fluorobenzyl)-1H-pyrazolo[3,4-b]pyridin-3-yl]pyrimidin-5-yl}carbamate 175 mul (1.713 mmol) of 1-chloro-2-methyl-2-propanol were initially charged in 6 ml of dichloromethane, 169 mg (0.571 mmol) of bis(trichloromethyl) carbonate were added and the mixture was cooled to 0¡ã C. Thereafter, 110 mul (1.37 mmol) of pyridine were added dropwise and the mixture was stirred at 0¡ã C. for 30 min. Subsequently, 400 mg (1.142 mmol) of the compound from example 1A were added, and then 2.93 ml (36.26 mmol) of pyridine. The mixture was stirred at 0¡ã C. for a further 30 min. Then a separate flask was initially charged with 87 mul (0.856 mmol) of 1-chloro-2-methyl-2-propanol in 3 ml of dichloromethane, and 85 mg (0.285 mmol) of bis(trichloromethyl) carbonate were added. After adding 55 mul (0.685 mmol) of pyridine, the mixture was stirred at 0¡ã C. for 30 min and the solution thus prepared was added to the mixture described above. After stirring at 0¡ã C. for a further 30 min, the reaction was stopped by addition of 10 ml of saturated aqueous sodium hydrogencarbonate solution and extracted three times with dichloromethane. The combined organic phases were dried with sodium sulfate and concentrated under reduced pressure. This gave 500 mg (84percent of theory) of the title compound, which were used without further purification in the subsequent experiments. LC-MS (method 2): Rt=0.86 min; MS (EIpos): m/z=485 (M+H)+.
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route,558-42-9, its application will become more common.
