Reaktionsschritte
To neat 4-(2-chloroethyl)-1-methyl-1H-pyrazole (50 g, 0.24 mol) was added a 25% aqueous solution of methylamine (1.15 L, 7.21 mol). The mixture was placed into an autoclave at 60° C. for 15 h. The resulting mixture was concentrated in vacuo, treated with aqueous solution of NaOH and extracted with DCM. The combined organic layers were concentrated in vacuo and purified by vacuum distillation to afford the title compound. b.p. 89-90° C./2 mm Hg.
