Reaction Steps

To a solution of 3-(7-cyclopropyl-4-methyl-3-oxo-2,3,4,10-tetrahydro-9-oxa-1,2,4a-triaza-phenanthren-6-yloxy)-azetidine-1-carboxylic acid tert-butyl ester (0.029 g, 0.068 mmol) in DCM (2 mL) was added TFA (0.35 mL) dropwise and the mixture was stirred at ambient temperature for 2 h. The solvent was removed in vacuo to give 6-(azetidin-3-yloxy)-7-cyclopropyl-4-methyl-2,10-dihydro-9-oxa-1,2,4a-triaza-phenanthren-3-one trifluoroacetic acid as a white solid (0.020 g, 90%). LC/MS (Table 1, Method 5) Rt=2.056 min.; MS m/z: 329 [M+H]+.
