実験手順
The product of part (i) above (2 g) in phosphorus oxychloride (6 ml) was heated at reflux for 1 h. The solution was then cooled (to 0°), and water (15 ml) was added slowly. The mixture was then heated at 100° for 10 min and then poured onto cracked ice. The resulting precipitate was filtered off, washed with water, and crystallised from methanol to give the title compound (1.6 g). IR includes peaks at 1690 cm-1 (CO2H) and 1620 cm-1 (CO).
