Versuchsvorschrift
97A was hydrogenated in MeOH with 10% Pd/C (20 mg) with a hydrogen balloon for 0.5 h. The Pd/C was removed by filtration. The filtrate was concentrated to give 97B (25 mg, 36% yield for two steps). 1H NMR (400 MHz, Methanol-d4) δ ppm 7.43-7.49 (m, 1H) 8.07 (d, J=2.64 Hz, 1H) 8.22 (d, J=1.76 Hz, 1H).
