実験手順
12.75 g of o-chloroaniline and 14.09 g of 1-acetylimidazolidin-2-one in 144 ml of POCl3 are stirred for 71 hours at 60°C. The mixture is worked up as described in Example 19 and 15.45 g, that is to say 65.3%, of the acetyl derivative of 2-(2'-chlorophenylamino)-2-imidazoline are obtained as a crystalline product, which, for analysis, is recrystallised from i-propanol and toluene. Melting point: 142°-143°C
