実験手順

To a solution of 3-(4-methyl-3-oxo-2,3,4,10-tetrahydro-9-oxa-1,2,4a-triaza-phenanthren-6-ylmethylene)-azetidine-1-carboxylic acid tert-butyl ester (0.1 g, 0.16 mmol) in MeOH (10 mL) was added Pd/C (10%, 0.02 g) and the mixture was stirred under H2 (50 psi) for 14 h. The reaction mixture was filtered and the filtrate was concentrated in vacuo and the residue was purified by preparative TLC (eluting with 50% EtOAc in petroleum ether) to give 3-(4-methyl-3-oxo-2,3,4,10-tetrahydro-9-oxa-1,2,4a-triaza-phenanthren-6-ylmethyl)-azetidine-1-carboxylic acid tert-butyl ester (0.075 mg, 69%) as a pale yellow powder. LC/MS (Table 1, Method 2) Rt=1.217 min; MS m/z: 409 [M+23]+.
