Procedure

A solution of methyl 4-(3-imidazo[1,2-a]pyridin-6-ylureido)benzoate (2.1 g, 6.77 mmol) in tetrahydrofuran (18.05 ml) and methanol (9.02 ml) was treated with 2N lithium hydroxide (13.53 ml, 27.1 mmol) and the reaction was allowed to stir at room temperature for 16 hours. The mixture was concentrated, redissolved in 225 mL water and acidified to ˜pH 4 with 3N hydrochloric acid. The suspension was filtered with water washes to give the title compound after vacuum drying.
