The reaction mixture was stirred at room temperature for 30 min. Methanol was added and the mixture was concentrated under reduced pressure. The residue was then triturated with diethyl ether (25 mL) and stirred for 1 h. The mixture was filtered through a frit, and the filter cake was collected and dried to afford the title compound as a beige solid.
