Reaction Steps
To a stirred solution of compound from Step 2, toluene-4-sulfonic acid 4-trityloxymethyl-cyclopent-2-enylmethyl ester (21.3 g, 40.59 mmol) in dimethylformamide (150 mL) was added sodium cyanide (3.58 g, 73.18 mmol) at room temperature and the reaction was stirred at 70° C. for 48 h. After cooling, the reaction mixture was extracted with ethyl acetate (2×250 mL), washed with water (2×100 mL), brine (50 mL) and dried (MgSO4). After filtration, the filtrate was concentrated and the residue was purified on a silica gel column using ethyl acetate in hexanes (0 to 30%), which afforded 14.96 g (97.1%) of desired product, (4-trityloxymethyl-cyclopent-2-enyl)-acetonitrile, as a colorless solid.
