Reaction Steps

Triphosgene (173 g, 0.58 mmol) was added to a solution of 2-Amino-5-bromobenzamide (250 mg, 1.162 mmol) in 1,4-dioxane (12 mL). The reaction was heated at 100° C. for 1.5 hours, cooled to room temperature and quenched with water (1 ml). The solid was filtered and washed with EtOAc twice to provide crude product (230 mg), which was used without further purification.
