실험 절차

1-Methyl-4-oxo-4,5-dihydro-1H-pyrrolo[3,2-c]pyridine-7-carboxylic acid methyl ester (1.25 g) and phenyl dichlorophosphate (12 ml) were heated at 180° C. under argon for 30 minutes. The reaction was allowed to cool at which point a precipitate formed. This was filtered off and washed with diethyl ether to yield the title compound as a grey solid (1.2 g).
