Reaction Steps

To a stirred solution of phenyl 3-fluoro-4-(2-(methylsulfonyl)ethyl)phenylcarbamate (90 mg, 0.267 mmol) and (1-(3-chlorophenyl)-3-cyclopropyl-1H-pyrazol-5-yl)methanamine (70 mg, 0.286 mmol) in THF (4 mL) was added N-ethyldiisopropylamine (0.087 mL, 0.507 mmol) and stirred for 1 h in a microwave (150° C., 7 bar). The reaction mixture was concentrated in vacuo and purified by CC (eluent: ethyl acetate/cyclohexane (2:1)) to give 1-[[2-(3-chlorophenyl)-5-cyclopropyl-2H-pyrazol-3-yl]-methyl]-3-[3-fluoro-4-(2-methylsulfonyl-ethyl)-phenyl]-urea (30 mg, 23%).
