実験手順
An intimate mixture of 3-(3-aminopropyl)pyrazole (4.7 g) and S-methylthiouronium sulphate (4.9 g) is fused at 140° C for one hour. After cooling, methanol is added and the filtered methanol solution is subsequently diluted with ethanol. The solid obtained is recrystallised from methanol-ethanol affording 3-(3-pyrazolyl) propylguanidine hemisulphate, m.p. 210° C.
