实验步骤: The procedure of Example 20 is followed using 3-phenylnaphthalene-1-carboxylic acid (4.3 g), thionyl chloride (20 ml) and N-methylbut-2-ylamine (1.5 g) in pyridine (20 ml) as the starting materials. After recrystallisation from petroleum ether, N-methyl-N-(1-methylpropyl)-3-phenylnaphthalene-1-carboxamide (2.8 g), melting at 125° C., is obtained. After recrystallisation from petroleum ether, N-methyl-N-(1-methylpropyl)-3-phenylnaphthalene-1-carboxamide (2.8 g), melting at 125° C. is obtained

实验步骤: While stirring, 15.2 g of N-2-butyl-N-methylamine is dripped into a solution of 22.4 g of α-chloro-α-(2,4-dichlorophenyl)-acetyl chloride (see a)) in 100 ml of dioxane. After the exothermic reaction has subsided, the mixture is stirred overnight and then poured into 700 ml of ice water; the resultant mixture is acidified with dilute hydrochloric acid and the oil which has precipitated is extracted 8 times, each time with 100 ml of dichloromethane. The extracts are combined, dried over magnesium sulfate and concentrated; there is obtained 17.2 g of α-chloro-α-(2,4-dichlorophenyl)-acetic acid-N-2-butyl-N-methyl amide as a colorless oil. After the exothermic reaction the mixture is stirred overnight the oil which has precipitated is extracted 8 times dried over magnesium sulfate concentrated
