Procedure

1.25 g of hydroxylamine hydrochloride and 1.8 g of triethylamine were added to a solution of 1.9 g of compound 66. The mixture was stirred at room temperature for 1 day. The solvent was removed under reduced pressure and 10% citric acid aqueous solution was added to the residue. The mixture was extracted with chloroform and the extract was washed with water. The extract was dried and the solvent was removed under reduced pressure to yield 1.86 g of title compound 67.
