    摘要: NEW MATERIAL:The compound of formula I (R1 and R2 are 1-3C alkyl; R3 is H or 1-3C alkyl; R4 and R5 are 1-8C alkyl; m and n are 1-7; R4 and R5 are not H at the same time) and its salt. EXAMPLE:3-(Diisopropylaminoethylamino)-2',6'-dimethylpropionanilide. USE:An antiarrhythmic agent free from strong side effect. PREPARATION:The compound of formula I can be produced by reacting the chloroalkylanilide derivative of formula II with the diamine derivative of formula III in a toluene solution of triethylamine under refluxing. The reaction is carried out in a solvent such as benzene, toluene, xylene, etc., for about 3-24hr under stirring while raising the temperature to the refluxing temperature of the solvent.
