Procedure

A 0° C. solution of imidazo[1,2-a]pyridin-6-amine (1 g, 7.21 mmol), N-ethyl-N-isopropylpropan-2-amine (2.51 ml, 14.42 mmol) and dimethylformamide (21.85 ml) was treated with a solution of 1-isocyanato-4-nitrobenzene (1.313 g, 8.00 mmol) in tetrahydrofuran (10.92 ml) which was added dropwise via syringe over 5 minutes. The reaction mixture was allowed to stir at room temperature for 6 hours, and water was added. The suspension was filtered with water washes to give the title compound after vacuum drying.
