Reaction Steps

To a cooled (0° C.) solution of 6-bromo-1,2,3,4-tetrahydro-[1,8]naphthyridine (6.4 g, 30.0 mmol) in DCM (75 mL) is added a trichloroacetyl isocyanate (3.8 mL, 31.5 mmol). After stirring for 1 h at 0° C., a solution of methanolic KOH (1M, 10 mL) is added. The resulting mixture is allowed to warm and stir at room temperature for 16 h. The reaction is concentrated and purified by silica gel column (0-100% EtOAc in heptane) to afford the title compound (7.4 g).
