3,5-dimethyl-1,3-oxazolidin-2-one

反応条件: temp:160.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: 1.10 g of 1,2-dichloropropane and 7.18 g of a 40% methylamine aqueous solution were charged in a 20 ml pressure vessel made of SUS316 and 2.11 g of a carbon dioxide gas was absorbed under a pressure of about 0.5 MPa, followed by heating at 160° C. for 4 hours. As a result, 3,4-dimethyl-1,3-oxazolidin-2-one and 3,5-dimethyl-1,3-oxazolidin-2-one were obtained in a total yield of 64% and 1,3,4-trimethylimidazolidin-2-one was obtained in a 23% yield. was absorbed under a pressure of about 0.5 MPa
