Reaction Steps

To a suspension of 3 (1 g, 3.07 mmol) in a mixture of water/methanol (1:1 v/v, 30 mL) was added sodium hydrosulfite (Na2S2O4, 4.3 g, 24.6 mmol). The suspension was refluxed for 5 h until all starting material has disappeared. Upon completion, the reaction mixture was cooled to room temperature and 50 mL of water were added. After 20 minutes, a light yellow solid was collected by filtration and washed with water. The solid was dried under vacuo to give 4 (725 mg, 74% yield), which was used in the next step without further purification.
