Anhydrous triethylamine (0.155 mL, 1.11 mmol) was added and the reaction was stirred at room temperature under an inert atmosphere over night. The reaction was quenched using 2 M hydrochloric acid (20 mL) and extracted with dichloromethane. The combined organic phases were washed with water, dried over magnesium sulfate and concentrated under vacuum to give 194 mg (91% yield) of the title compound.
