Reaktionsschritte

2.5 g of 60% sodium hydride was suspended in 50 ml of benzene and a mixture of 5.6 g of 4methylcyclohexanone and 5.4 g of methoxyethyl acetate was added dropwise thereto under cooling. After stirring at room temperature for two hours, 20 ml of water was added and the pH value of the reaction mixture was adjusted to 3 with concentrated hydrochloric acid. After removing the benzene phase the aqueous phase was extracted with ether. The benzene solution and the ether solution were combined, washed with water, dried and concentrated to give 7.4 g of crude 2-methoxyacetyl4-methylcyclohexanone. This crude product was subjected to the subsequent step.
