With the rapid development and complex challenges of chemical substances, the synthesis of new drugs is usually one of the most effective ways to increase yield.100-86-7, name is 2-Methyl-1-phenyl-2-propanol, molecular formula is C10H14O, molecular weight is 150.22, as common compound, the synthetic route is as follows.category: alcohols-buliding-blocks
100.6 ml of concentrated sulfuric acid (9.4 eq.) are placed in a 500 ml three-necked flask equipped with a condenser and a thermometer, followed by cooling to a temperature in the region of 5- 10C. A mixture containing 30 g of methyl- 1 -phenyl-2-propanol (1 eq.) and 9.83 g of acetonitrile (1 eq.) is added dropwise. The mixture is stirred for 5 minutes at a temperature in the region of 5-10C and then for 5 hours at room temperature (monitoring by TLC, 95/5 CH2Cl2/MeOH). (0210) The mixture is then poured into 1 litre of water and extracted with 100 ml of toluene. The aqueous phase is basified to pH 8.5 with ammonium carbonate and then extracted twice with 500 ml of MTBE (methyl tert-butyl ether). The organic phase is dried over Na2S04, filtered, evaporated to dryness and then dried under vacuum over P205. 27 g (78% yield) of compound (a) are obtained in the form of a yellow liquid. (0211) The NMR and mass analyses are in accordance with the expected structure.
At the same time, in my other blogs, there are other synthetic methods of this type of compound,100-86-7, 2-Methyl-1-phenyl-2-propanol, and friends who are interested can also refer to it.
