Procedure

3.91 g (9.5 mmol) of the above product was added to a solution of L(+)-tartaric acid (3.54 g, 23.6 mmol) in water (60 ml) and the solids were dissolved by heating to reflux. The hot solution was treated with decolorizing carbon, filtered and allowed to cool. The separated crystals were collected, washed with water and acetonitrile and dried to give the ditartrate-trihydrate of the title compound, mp. 185°-190° C., yield of the salt formation: 66.9%.
