Procedure

To a suspension of 243 (150 mg, 0.547 mmol in DMF (6 mL) was added NaH (66 mg, 1.64 mmol). and the reaction mixture was stirred at 0° C. for 1 hour. Chloromethyl methyl ester (132 mg, 1.641 mmol) was added drop wise and the mixture was stirred at room temperature over night. MeOH (2 mL) was added and the mixture was stirred for an additional hour and partitioned between EtOAc and water. The organic phase was collected, dried over anhydrous sodium sulfate and concentrated under reduced pressure to afford title compound 244 (86 mg, 49% yield, crude) as an orange solid. MS (m/z): 319.1 (M+1).
