Procedure

20 Grams of 6-(β-chloropropionyloxy)-3,4-dihydrocarbostyril, 60 g of pulverized anhydrous aluminium chloride, 6 g of sodium chloride and 6 g of potassium chloride were mixed together and the mixture was melted by heating and stirred at 150°-170° C. for 1 hour. The reaction mixture was poured into ice-water and allowed stand overnight to obtain crystalline precipitates. The precipitates were collected by filtration, washed with water and dried, then recrystallized from methanol to obtain 12 g of 6-hydroxy-7-(3-chloropropionyl)-3,4-dihydrocarbostyril in white crystals. Melting point: 205°-208° C.
