Reaction Steps
2-Hydroxy-2',4'-dichlorochalcone, as described in Arch. Pharm. 295, 16 (1962), was cyclized to the flavanone by the procedure described in Bull. Soc. Chem. France 674 (1973). Two recrystallizations from methanol gave 3 g of 2',4'-dichloro flavanone as pale tan crystals, m.p. 91°-92° C.
