Reaction Steps

To a solution of (R)-3-hydroxy-pyrrolidine (2.00 g, 22.95 mmol) (Aldrich) and Et3N (9.00 g, 88.93 mmol) in 45 mL of CH2Cl2 at 0° C. it was added propargyl bromide (3.00 g, 25.21 mmol) in a dropwise manner. Upon completion of the addition, the reaction mixture was filtered and the filtrate was washed with brine, dried over Na2SO4 and concentrated. (R)-3-Hydroxy-1-prop-2-ynyl-pyrrolidine was obtained after Krugerhor distilation (Yield 700 mg, 24%).
