Versuchsvorschrift

1.12 g of 60% sodium hydride was added to 2.5 g of ethyl acetate and 1.78 g of a benzene solution of 4-methoxycyclohexanone was added thereto. After reacting at 40° C. for three hours, methanol was added to thereby decompose excessive sodium hydride and the reaction mixture was poured into water, neutralized with hydrochloric acid and extracted with ether to give 1.02 g of 2-acetyl4-methoxycyclohexanone. NMRδTMSCCl4 : 2.06 (3H, s). 1.7-2.5 (8H, s), 3.28 (3H , s), 3.4 (1H, m) and 15.9 (1H, s).
