Conditions

Temperature: 70 °C

Procedure

The title compound from Step A above (14.54 g, 44.8 mmoles) was dissolved in anhydrous DMF (100 mL) and sodium imidazole (6.52 g, 72.4 mmoles) was added. The mixture was heated under argon at 70° C. for 2 h. The solution was evaporated to dryness and chromatographed on silica gel using 2% (10% conc. NH4OH in methanol)-dichloromethane as the eluant to give the title compound (8.92 g, 68%):
