Procedure

34.9 Grams of n-butylamine is mixed with 50 g of 2,2'-azobis (2-methyl propionate), and 10 g of 28% sodium methoxide solution in methanol is dropwise added thereto with stirring, followed by conducting a reaction at room temperature with stirring for 6 hours and keeping standing overnight. 100 Milliliter of water is added to the reaction solution and cooled to 10° C. to precipitate crystals. The crystals are recovered by filtration and dried to give 58.0 g (yield 85.5%) of 2,2'-azobis [N-butyl-2-methyl propionamide] as pale yellow crystal. The solubility is shown in Table 1.
