Procedure

The compound of Example 3 (0.10 g, 0.155 mmol) was stirred with 0.5 ml of formamide and 0.2 ml of dimethyl formamide (DMF) for 1.5 hours at 170° C. The reaction mixture was cooled and poured into ethyl acetate/water. The ethyl acetate layer was washed with brine, dried over sodium sulfate, and concentrated under vacuum. The residue was flash chromatographed on silica gel using 10:1 to 4:1 hexane/ethyl acetate eluant to give the product, 0.057 g (0.109 mmol), 35%.
