Reaction Steps

3-(2-Amino-4-chloro-phenyl)-4H-[1,2,4]oxadiazol-5-one (400 mg, 1.92 mmol) was dissolved in 20 ml dry THF and 3-trifluoromethyl-phenyl-isocyanate (450 mg, 2.40 mmol) was added and the reaction stirred for 16 hours. The solvent was reduced under vacuum and the product recrystallised from ethyl acetate and heptane to yield 480 mg (63%) of off-white crystalline solid (m.p. 246-248; decomposition).
