Product 1

HCID 1109982-MethoxycyclohexanoneYield 90%

Procedure

2-methoxycyclohexanone was prepared by dissolving 30 gm. 2-chlorocyclohexanone in 160 ml. methanol and heating the solution in a sealed vessel at 125° C. for approximately four hours. The reactionmass was then cooled and the methanol removed by distillation at reduced pressure. After most of the methanol was distilled off, the residue containing the 2-methoxycyclohexanone was diluted with methylene chloride and extracted with an aqueous solution of sodium hydroxide. After distillation a yield of 90-95% 2-methoxycyclohexanone was obtained.
