実験手順
With gentle heating, 22a (1.5 g; 5.4 mmol) was dissolved in methanol (15 ml). The solution was cooled to room temperature, HCl-containing methanol (20 ml) was added and the mixture was transferred into a two-necked flask. Pd—C 10% (150 mg) was introduced into the initial charge. The reaction vessel was evacuated using an oil pump, and H2 was then introduced via a gas inlet capillary (4×). At room temperature, the suspension was shaken in a closed three-necked flask under an atmosphere of H2 (240 strokes/min) until no more starting material could be detected by thin-layer chromatography (6 h). The suspension was filtered and the catalyst was washed with plenty of methanol. The combined filtrate was concentrated and the mustard-colored solid-amorphous residue was dried using an oil pump. The crude product was used without further purification for the next reaction step.
