Reaction Steps

Methyl 2-(4-hydroxy-1-methyl-2-oxo-1,2-dihydroquinoline-3-carboxamido)acetate (0.94 g, 1.4 mmol), methanol (0.33 ml, 8.1 mmol) and triphenyl phosphine (0.94 ml, 4.1 mmol) were placed in a 50 mL round bottomed flask with 25 mL of THF. The flask was placed in an ice bath. Diethyl azodicarboxylate (0.64 ml, 4.1 mmol) was added dropwise. A white solid was filtered and this solid was purified by silica flash chromatography (0-3% MeOH/DCM) to give the desired product.
