Procedure

The material from Example 32 was diluted with toluene then combined with phosphorous oxychloride and heated at reflux overnight. The reaction mixture was concentrated under vacuum. The residue was diluted with water,basified with ammonium hydroxide then extracted several times with methylene chloride. The methylene chloride extracts were combined, dried over magnesium sulfate then concentrated under vacuum. The residue was purified by silica gel column chromatography eluting with 10-40% ethyl acetate in hexane to provide the desired product.
