Electric Literature of 110-73-6, 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. 110-73-6, name is 2-(Ethylamino)ethanol. A new synthetic method of this compound is introduced below.
To a vial containing 6-[4-({[6-(3-fluorophenyl)pyridin-3-yl]carbonyl}amino)piperidin-1-yl]nicotinic acid (63.07 mg, 0.15 mmol) was added 0.375 mL of DMA, EDC (31.6 mg, 0.16 mmol), HOBt (20.3 mg, 0.15 mmol), NMM (0.04 mL, 0.37 mmol) and 2-(ethylamino)ethanol (13.4 mg, 0.15 mmol). The reaction mixture was stirred at room temperature for 12 hours and then diluted with water and ethyl acetate. The layers were separated and the organic layer collected and concentrated to give an oil, which was purified by RP-HPLC to give N-ethyl-6-[4-({[6-(3-fluorophenyl)pyridin-3-yl]carbonyl}amino)piperidin-1-yl]-N-(2-hydroxyethyl)nicotinamide (32 mg, 43%). HRMS (TOF, ES+) calculated for C27H30FN50 +H: 492.2333; observed 492.2611.
At the same time, in my other blogs, there are other synthetic methods of this type of compound,110-73-6, 2-(Ethylamino)ethanol, and friends who are interested can also refer to it.
