To a stirred solution of 66.15B (1.00 g, 3.3 mmol) in acetic acid (2.00 mL, 35 mmol) at 23° C. was added DME (15.00 mL, 144 mmol), EtOH (10.00 mL), followed by tin(II) chloride (4.7 g, 25 mmol). The mixture was heated at 60° C. for 17 hours. After which, the reaction was cooled to room temperature. The reaction was diluted with water and extracted three times with EtOAc. After drying over anhydrous magnesium sulfate and filtering, the organic solvent was removed under reduced pressure to give the product 66.15C (0.90 g, 100% yield).
