You can simply reduce it with some reducing agent or hydrogenate it if there is no other reducible group

Try La(OTf)3 in methanol. Use 1 mM lanthanum triflate, 1 mM methoxide and your substrate at ~100 mM at room temperature. The reaction will give you methyl acetate and your alcohol. If you want the reaction to go faster simply use more La/methoxide but keep the ratio 1:1. Other forms of La that can be used include perchlorate salts and iodides but LaCl3 or the oxide will NOT work. See Organic and Biomolecular Chemistry 2005, 65. The second order rate constant for reaction of isopropyl acetate is about 0.004 M-1s-1. And for the record if you combine La and methoxide in a ratio of 1:1 the pH will be ~8.7 which is neutral pH in methanol.

thak u for the information,

I stirred with simple methanol for so many days but there is no use.

now i have try LAH reaction.

In many cases this has worked : 1)Add catalytic amount of K2CO3 to the methanolic solution and stirr to completion. 2)Boric acid added to methanolic solution also does the job through ester exchange. Good Luck!

Try with grignard reagent if any Grignard reactive group is not present.
