Reaction Steps

A solution containing 5-{[5-cyano-2-propyl-4-(trifluoromethyl)-1H-indol-1-yl]methyl}-2-furancarboxamide (Example 271B) (0.388 g, 1.03 mmol), pyridine (10 mL) and CH2Cl2 (25 mL) was cooled to 0-5° C. This mixture was mixed with POCl3 (0.792 g, 5.17 mmol) and the resulting mixture was stirred at rt for 2 h. The reaction mixture was then partitioned between CH2Cl2 and saturated NaHCO3. The organics were washed with 1.0N HCl, dried (MgSO4) and concentrated to dryness. The residue was purified by flash chromatography (0-10% EtOAc-hexanes gradient) to afford a pure product (0.204 g, 55% yield): MS (ES) m/z 357 (M+).
