Some common heterocyclic compound, 41365-75-7, name is 1-Amino-3,3-diethoxypropane, molecular formula is C7H17NO2, traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route. category: ethers-buliding-blocks
3,3-diethoxypropan-1-amine (6 g, 40.76 mmol, 1.00 equiv) was dissolved in 1,4- dioxane (30 mL) in the presence of TEA (4.45 g, 43.98 mmol, 1.08 equiv), then cooled to0C. (Boc)20 (9.6 g, 43.99 mmol, 1.08 equiv) diluted in 20 mL of 1,4-dioxane was added drop-wise. The solution was agitated 2 hours at 0C then overnight at ambient temperature before being neutralised with 10 mL of water. The pH was adjusted to 5 with HC1 (1 %). The solution was extracted 3 times with 50 mL of EtOAc. The organic phases were combined, dried over sodium sulfate, filtered and concentrated to yield 8.21 g (81 %) of compound 1ZDin the form of a pale yellow oil.
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 41365-75-7, its application will become more common.
