Reaction Steps
A solution of Example 252E (1.2 g, 5 mmol) in POCl3 (30 mL) was heated to reflux for 30 minutes. The excess POCl3 was removed under vacuum and the remaining product was purified by flash column chromatography on silica gel with 4:1 ethyl acetate/hexanes to provide the desired product. MS (ESI) m/e 248 (M+H)+.
