Procedure

A mixture of compound (4) (32.1 g, 0.144 mol) and 85% phosphoric acid (30 mL) was heated at 130° C. for 30 minutes. The resulting mixture was cooled to room temperature, poured into ice water with vigorous stirring, and the resulting precipitate was filtered and dried under vacuum to afford 21.6 g (67%) of compound (5) as a pink solid.
