実験手順

A mixture of methyl 5-({5-[(4-methyl-1-piperazinyl)methyl]-2-nitrophenyl}amino)-3-({(1R)-1-[2-(trifluoromethyl)phenyl]ethyl}oxy)-2-thiophenecarboxylate (0.24 g, 0.415 mmol), 5% Pd/C (0.144 g), HCl (1.25 M in MeOH, 0.034 mL, 0.043 mmol), trimethylorthoformate (1.66 mL, 15.2 mmol) in toluene (0.58 mL) was hydrogenated under a H2 atmosphere at 1.1 bar pressure overnight. The vessel was purged with N2 and the reaction mixture was analysed by HPLC to confirm presence of the title compound which was not purified, but used crude in the next step. LRMS found m/z [ES+] 549.
