PROCEDURE
实验过程
200 mg of Compound 31 was dissolved in 4 ml of ethanol, 2 ml of concentrated hydrochloric acid was added and the mixture was heated at reflux for 4 hours. The reaction solution was cooled on ice and adjusted to pH 8 by addition of a 10N aqueous solution of sodium hydroxide thereto, and the precipitated crystals were collected by filtration and subjected to preparative thin layer chromatography (chloroform:acetone=20:1) to give 63 mg (34%) of Compound 32.
