Reaction Steps
A mixture of 1-(3-trifluoromethylphenyl)-4,5-dihydro-1H-pyrazol-3-amine (0.23 g), 4-methoxyaniline (0.37 g) and p-toluenesulphonic acid (0.17 g) was heated in an oil bath at 140° under nitrogen for 15 minutes. The reaction was cooled, dilute hydrochloric acid and ether added and the organic phase separated, dried over sodium sulphate, filtered and evaporated to leave a yellow solid, which on trituration with pentane gave the colourless title compound (0.1 g) m.p. 127°-8°.
