実験手順

A mixture of 515 mg of the product of Step E and 0.6 ml of phosphorous oxychloride was heated for 2 hours at 120° C. and the mixture was cooled. 10 ml of water were added and the solution was alkalized to pH 9 with concentrated ammonium hydroxide. Extraction was carried out twice with methylene chloride and the extracts were washed with a saturated solution of sodium chloride, dried and evaporated to dryness. The residue was dissolved in 30 ml of ethanol and treated for 15 minutes at reflux in the presence of activated charcoal, followed by filtering on hyflosupercel to obtain 511 mg of the desired product.
