Reaction Conditions:

with hydrogenchloride in water;acetone at 25 - 30; for 0.25 h;

Steps:

2 Example-2: Preparation of 7-methoxy-3,4-dihydronaphthalen-2(lH)-one
Acetone (5 ml) was added to 2,7-dimethoxy-l,4-dihydronaphthalene (0.5 gms) at 25- 30°C and stirred for 10 minutes at the same temperature. 5% aqueous hydrochloric acid was added to the reaction mixture at 25-30°C and stirred for 15 minutes at the same temperature. Water and dichloromethane were added to the reaction mixture at 25-30°C. Both the organic and aqueous layers were separated and extracted the aqueous layer using dichloromethane. Distilled off the solvent from the organic layer under reduced pressure to get the title compound. Yield: 0.42 gms.
