To a stirred suspension of 125 g of α-amino-ε-caprolactam, 118 g of triethylamine and 600 ml of chloroform, 288 g of chlorotriphenylmethane was added under ice-cooling. The mixture was further stirred for an hour under the same conditions, followed by 2 hours' stirring at room temperature. Thus resulting precipitates were collected by filtration, washed thoroughly with acetone and dried to provide 330 g of α-triphenylmethylamino-ε-caprolactam, m.p. 240-241° C.
