Title:
METHOD FOR DEPROTECTING 9-FLUORENYLMETHOXYCARBONYL GROUP FROM SUBSTRATE
Document Type and Number:
Japanese Patent JP2007008887
Kind Code:
A
Abstract:
To provide a method for deprotecting 9-fluorenylmethoxycarbonyl group from a substrate protected with 9-fluorenylmethoxycarbonyl group in a short time and high yield by suppressing decomposition of the substrate without substantially using a base causing complicatedness of separation.
The method for deprotecting 9-fluorenylmethoxycarbonyl group from the substrate comprises bringing the substrate protected with 9-fluorenylmethoxycarbonyl group into contact with hydrogen by wet system in the presence of a palladium-carbon catalyst in which palladium is fixed on carbon particles having ≥1,000 m2/g specific surface area.
