The mixture was heated at 75° C. for 2 hours, then was poured into cold water (30 ml). The solids formed were collected, rinsed with water and washed with dichloromethane (2×10 ml), the solids were further purified by column chromatography, eluted with 5% DMF in dichloromethane to give the title compound as a white solid (0.125 g).
