Related Products of 645-36-3, As we all know, there are many different methods for the synthesis of a compound, and people can choose the synthesis method that suits their own laboratory according to the actual situation. 645-36-3 name is 2,2-Diethoxyethanamine, This compound is widely used in many fields, so it is necessary to find a new synthetic route. The downstream synthesis method of this compound is introduced below.
A mixture of 2-bromo-5,6-dihydro-4H-pyrazolo[1,5-d][1,4]diazepine-7(8H)-thione (265.0 mg, 1.07 mmol), 2,2-diethoxyethan-1-amine (1.42 g, 10.7 mmol) and silver carbonate (590 mg, 2.14 mmol) in tetrahydrofuran (10 mL) was stirred at 80 C. for 1 h. The solvent was concentrated under vacuum. The residue was purified by reverse-phase column eluting with water (0.05% TFA)/CH3CN (85/15) to afford 2-bromo-N-(2,2-diethoxyethyl)-5,8-dihydro-4H-pyrazolo[1,5-d][1,4]diazepin-7-amine (295 mg, 80%) as a brown oil. LCMS (ESI) [M+H]+=345.0.
At the same time, in my other blogs, there are other synthetic methods of this type of compound, 2,2-Diethoxyethanamine, and friends who are interested can also refer to it.
