Procedure
A mixture of 1-(2-chloro-4-fluoro-5-nitrophenyl)-3-methyl-s-triazine-2,4,6(1H,3H,5H)-trione (28.5 g, 0.09 mol) and 5% platinum on activated carbon (1 g) in ethyl acetate is hydrogenated at 55 psi until hydrogen uptake is complete. The reaction mixture is then filtered and concentrated in vacuo to give the title product as a white solid, mp 244°-245° C.
