実験手順
Platinum oxide (0.46 g) was added to a solution of 8-(6-methoxy-quinazolin-4-ylethynyl)-1,4-dioxa-spiro[4.5]decan-8-ol (0.96 g, 2.88 mmol) in EtOH (40 ml) and THF (10 ml), and hydrogenation was carried out under a hydrogen atmosphere (1 bar). The reaction mixture was stirred in the presence of activated carbon (5 g) and filtered. The filtrate was concentrated to dryness by rotary evaporation. The residue was purified by column chromatography on silica gel (EtOAc and then EtOAc:MeOH 9/1).
