実験手順

To a solution of 3-[4-methyl-3-oxo-7-trifluoromethyl-2-(2-trimethylsilanyl-ethoxymethyl)-2,3,4,10-tetrahydro-9-oxa-1,2,4a-triaza-phenanthren-6-ylmethylene]-azetidine-1-carboxylic acid tert-butyl ester (0.072 g, 0.127 mmol) in CH3OH (10 mL) was added Pd(OH)2/C (0.02 g) and the mixture was stirred under an atmosphere of H2 (50 psi) for 14 hr. The reaction mixture was filtered and the filtrate was concentrated to give 3-[4-methyl-3-oxo-7-trifluoromethyl-2-(2-trimethylsilanyl-ethoxymethyl)-2,3,4,10-tetrahydro-9-oxa-1,2,4a-triaza-phenanthren-6-ylmethyl]-azetidine-1-carboxylic acid tert-butyl ester (0.052 g, 70%) as a pale yellow powder. LC/MS (Table 1, Method 2) Rt=1.502 min.; MS m/z: 607 [M+23]+.
