Participants

Reaction Steps

2-Chloro-5-(4-[1,2,3]triazol-1-yl-but-1-ynyl)-pyrimidine (2.52 g, 10.8 mmol) is dissolved in ethyl acetate (210 ml) and hydrogenated for 2.5 h at r.t. in the presence of palladium on calcium carbonate (10%, 2.55 g). The reaction mixture is filtered and concentrated in vacuo to yield 2-chloro-5-(4-[1,2,3]triazol-1-yl-butyl)-pyrimidine as a colorless solid. Yield 2.15 g (84%)
