A suspension of compound 125 (3.1 g, 9.5 mmol) in 30 mL of 5% NaOH aqueous solution was stirred in an oil bath of 90° C. for 8 hrs and cooled down to room temperature. Ice was added while stirring to the reaction mixture. The resulting suspension was filtered, and the cake was washed with cold water (10 mL×3) and further dried in vacuo to afford the desired product 113 as an off-white powder.
