Reaction Steps

Pyrrolidine (7.8 ml, 94 mmol) was added dropwise to a solution of 4-chlorobut-2-yn-1-ol (4.74 g, 45 mmol) in toluene (40 ml) and the mixture stirred and heated at 60° C. for 1 hour. The volatiles were removed by evaporation and the residue was purified by chromatography eluting with methylene chloride/methanol (96/4) to give 4-(pyrrolidin-1-yl)but-2-yn-1-ol (4.3 g, 69%).
