実験手順
Using a procedure similar to Example 3, step (c), 4,4-difluoro-1-(2-nitro-phenyl)-piperidine (128 mg, 0.520 mmol, as prepared in the previous step) was stirred with 80 mg 5% Pd—C in 4 mL of MeOH under H2 to afford 76 mg (69%) of the title compound as a dark oil, which was used immediately due to apparent instability. Mass spectrum (ESI, m/z): Calcd. for C11H14F2N2, 213.1 (M+H), found 213.1.
