Some tips on 80-65-9

80-65-9 3-Aminooxazolidin-2-one 65725, aoxazolidine compound, is more and more widely used in various.

With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.80-65-9,3-Aminooxazolidin-2-one,as a common compound, the synthetic route is as follows.

EXAMPLE II 3-[(6-Methoxy-4-chromanylidene)amino]-2-oxazolidinone A solution of 62 g (0.61 mole) of 3-amino-2-oxazolidone in 650 ml of benzene was treated with 15 drops of HCl (isopropanol) solution using mechanical stirring, and refluxed until all water was removed via a Dean-Stark trap. The solution was then treated with 107 g (0.60 mole) of 6-methoxy-4-chromanone and refluxed for 11.5 hr. A 9.6 ml portion of water (theory: 10.8 ml) was collected. The reaction mixture was stripped of benzene under the water pump. The residue was taken up in 200 ml of 1:1 isopropanol:ether, stored 24 hr at room temperature, refrigerated overnight and filtered. The resultant cream-colored solid was washed with 125 ml of isopropanol, ether, and dried. M.p. 54-64; yield: 115 g (73%). The crude product was recrystallized from 340 ml of isopropanol (Darco), washed with 75 ml of isopropanol, ether and dried. M.p. 67-71; Yield: 88 g (56%). Anal. Calcd. for C13 H14 N2 O4: C, 59.53; H, 5.38; N, 10.68. Found: C, 59.57; H, 5.28; N, 10.56.
