Methyl p-toluenesulfonate → HCID 178433612, compound

Participants

Reaction Steps

A mixture of 0.6 g of 2-amino-3-hydroxyquinoline, 3.8 mL of trimethylorthoacetate and 0.1 g of p-toluenesulfonic acid is heated at 60° C. for 7 hours. The reaction mixture is then diluted with ethyl acetate, washed with sodium bicarbonate, and purified by column chromatography on silica gel to yield 0.28 g of 2-methyloxazolo[4,5-b]quinoline. The quinoline is heated with one equivalent of methyl tosylate at 70° C. for one hour to generate the product.
