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.124-68-5, name is 2-Amino-2-methyl-1-propanol, molecular formula is C4H11NO, molecular weight is 89.1362, as common compound, the synthetic route is as follows.HPLC of Formula: C4H11NO
Example 24d 2-amino-6-(2-amino-2-methylpropoxy)benzonitrile To a solution of 2-amino-2-methylpropan-1-ol (14.4 g, 161 mmol) in anhydrous THF (150 mL) was added NaH (6.8 g, 161 mmol, 60% in mineral oil) in small portions at 0 C. under nitrogen. The mixture was stirred at 0 C. for 30 minutes and then stirred at room temperature for another 30 minutes. The solution was cooled down to 0 C. again, and to this solution was added dropwise a solution of 2-amino-6-fluorobenzonitrile (20.0 g, 147 mmol) in anhydrous THF (50 mL). The reaction mixture was then refluxed overnight under nitrogen. The reaction mixture was cooled down to room temperature and carefully quenched with aqueous NH4Cl solution and extracted with ethyl acetate (3*). The combined organic layers were washed with brine, dried over MgSO4, filtered and concentrated. The crude mixture was purified by chromatography on silica gel eluting with 10% MeOH in DCM to give the title compound as yellow solid (23.4 g 71%). 1H NMR (400 MHz, DMSO-d6) delta 1.08 (s, 6H), 3.15 (s, 2H), 3.64 (s, 2H), 5.98 (s, 2H), 6.13 (d, J=8.0 Hz, 1H), 6.31 (d, J=8.4 Hz, 1H), 7.15 (t, J=8.4 Hz, 1H). MS 236 (MH+).
At the same time, in my other blogs, there are other synthetic methods of this type of compound,124-68-5, 2-Amino-2-methyl-1-propanol, and friends who are interested can also refer to it.
