Reaction Steps

30.06 g (300.0 mmol) of 2-methylpiperazine were combined with 4.51 ml (50.0 mmol) of 2-bromothiazole. This mixture was fused and refluxed 5 min. The reaction mixture was cooled and taken up in 10% strength hydrochloric acid and washed with EA. The aqueous phase was set to pH>12 with a 10% strength aq. NaOH solution and then extracted with EA. The organic phase was dried over MgSO4 and conc. in vacuo. There were obtained 8.26 g (45.1 mmol, 90%) of 3-methyl-1-thiazol-2-ylpiperazine.
