The solution was added with anhydrous potassium carbonate 3.6 g and after heating upto 110° C. dropped with benzyl bromide 4.1 g during one hour to be stirred thereafter at a temperature of 140° C. for 4 hours. The reaction solution was taken into a large amount of water to precipitate crystal, which was dried to obtain the captioned product in the amount of 6.6 g.
