Experimental procedure for the synthesis of alcohols

To the ice cold solution of ketone (10 mmol) in methanol (20 mL), sodium borohydride (5

mmol) was slowly added under stirring. Then, the mixture was further stirred for 1 h at 0 oC

followed by 1 h at room temperature. After completion of the reaction monitored by TLC,

mixture was extracted with ethyl acetate and washed with water. Evaporation of the ethyl

acetate gave alcohol up to 95-99% yields.
