Reaction Steps

A suspension of 4-hydroxy-7-methyl-5,6,7,8-tetrahydrocarbostyril, (1.608 g; 0.009 mole) in glacial acetic acid (10 ml) was treated with concentrated nitric acid (2.5 ml; d 1.42) and the clear solution heated at 100° C until the exothermic reaction set in (ca 7 mins). After rapid cooling water (40 ml) was added and the yellow solid filtered off and recrystallised from ethanol; acetic acid, m.p. 238° (d).
