Benzaldehyde → Thiazolo[4,5-c]quinoline, 2-phenyl-

Participants

Reaction Steps

A mixture of 20.52 g (0.1 mole) of 3-amino-4-mercapto-quinoline-hydrochloride, 10.61 g (0.1 mole) of freshly distilled benzaldehyde and 200 ml of ethanol is refluxed for 2 hours, whereupon air is bubbled through the reaction mixture for several days. The precipitated crystals are filtered and recrystallized from ethanol. Thus 13.5 g of 2-phenyl-thiazolo[4,5-c]quinoline are obtained. The melting point of this product is identical with that of the compound prepared according to Example 5.
