Procedure

A solution of 4-(3-bromophenyl)but-3-yn-1-ol (21 g) in ethanol (1000 ml) was hydrogenated over platinum oxide (500 mg) for 4 h. The catalyst was removed by filtration and the filtrate was evaporated to give the title compound (18 g) tlc (SiO2) diethyl ether Rf=0.38.

Workup

  1. customThe catalyst was removed by filtration
  2. customthe filtrate was evaporated
