Application of 117009-97-9,Some common heterocyclic compound, 117009-97-9, name is Benzyl 1,4-diazepane-1-carboxylate, molecular formula is C13H18N2O2, 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.
Compound BB-18-3 (1.8g crude) was dissolved in dilute hydrochloric acid (6M, 40mL) was stirred until uniform, slowly under nitrogenwas added dropwise sodium nitrite solution (2N, 17mL), then stirred at room temperature for 1 hour, 50mL of water was added, extracted with ethyl acetate(60mL ¡Á 3).The combined organic phases with saturated brine (20 mL), dried over anhydrous sodium sulfate, the solvent was removed under reduced pressure to give the titlecompound BB-18-4 (2g crude) was used directly in the next step without further purification.
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route Benzyl 1,4-diazepane-1-carboxylate, its application will become more common.
