In the chemical reaction process, reaction time, type of solvent, can easily affect the result of the reaction, thereby determining the yield and properties of the reaction product. An updated downstream synthesis route of 17994-94-4 as follows. Recommanded Product: 17994-94-4
General procedure: To a mixture of aldehyde (1 mmol) and amine/amine hydrochloride (1 mmol) in anhydrous CH2Cl2 (10 mL) was added triethylamine (2.5 mmol) at rt, and the resulting solution was stirred vigorously for 1 h. To this was then added (Boc)2O (1.2 mmol) followed by sodium triacetoxyborohydride (2 mmol). The reaction was stirred for an additional 4 h at rt, quenched with saturated NaHCO3 solution, and extracted with CH2Cl2. The combined organic fractions were washed with brine, dried over Na2SO4, and concentrated under reduced pressure. The crude residue was purified by flash chromatography (95:05?50:50, hexanes/EtOAc) to afford the N-Boc secondary amine. Most of the title compounds were present as a mixture of rotational isomers in their 1H and 13C NMR spectra.
According to the analysis of related databases, 17994-94-4, the application of this compound in the production field has become more and more popular.
