実験手順
To a solution of methyl 6-(4-biphenylylmethoxy)nicotinate (2.0 g) in methanol (20 ml)/THF(40 ml) was added iN aqueous sodium hydroxide (13 ml) at room temperature. After stirring at room temperature for 4 hr the reaction mixture was diluted with 1 N hydrochloric acid (13 ml) and concentrated. The precipitate was collected by filtration and washed with water and diethyl ether sequentially to obtain the titled compound (1.6 g) as amorphous powder.
