Reaction Steps

A solution of 4-(4-methyl-3-oxo-2,3,4,10-tetrahydro-9-oxa-1,2,4a-triaza-phenanthren-6-yl)-piperidine-1-carboxylic acid tert-butyl ester (0.020 g, 0.050 mmol) in DCM (6 mL) and TFA (1 mL) was stirred at ambient temperature for 1.5 h. The solvent was removed in vacuo to give 4-methyl-6-piperidin-4-yl-2,10-dihydro-9-oxa-1,2,4a-triaza-phenanthren-3-one trifluoroacetic acid as a pale yellow solid (0.019 g, 99%).
