Sir the mixture at room temperature for 15 h then dilute with water causing a solid to precipitate from solution. Collect the solid by filtration, wash with water and dry on the filter pad. Triturate the crude product with methylene chloride and dry on the filter pad to provide 0.020 g of the title compound as a powder. MS, electrospray 448.96 (M+H), rt. 1.13 min.
