Example 10
Preparation of N,N-dibutyl lactamide
Methyl lactate (1 g) obtained by the method of Examples 1?6, N,N-dibutyl amine (1.5 g) and methanol (2 g) were introduced into a reactor at 0° C. under Ar atmosphere, the temperature was increased to 60° C., and the mixture was reacted for 20 hours.
And then, the reaction mixture was cooled to room temperature, and N,N-dibutyl lactamide was obtained by fractional distillation (0.9 g, yield 64%).
