Participants

Reaction Steps

A solution of thionyl chloride (0.5 g, 4.46 mmol) in toluene (2 mL) was added dropwise to the product of Step A (1.1 g, 2.23 mmol) in toluene (10 mL) at 65° C. The mixture was cooled to ambient temperature and then poured into 1N hydrochloric acid (50 mL). The resulting mixture was extracted with ethyl acetate (2×25 mL). The combined extracts were dried and evaporated to give the title product as an oil (1.0 g, 95% yield).
