Reaction Steps

To a solution of the nitrile from Step 2 (415 mg, 1.24 mmol) in toluene (4.5 mL) at -78° C. there was added diisobutyl aluminum hydride (1M) in toluene (1.9 mL, 1.9 mmol) and the mixture was stirred at -78° C. for 2 hours; methanol (2 mL) was added and the mixture allowed to warm to room temperature. After partition between ether and water, the residue from evaporation of the organic fraction was chromatographed on silica gel eluting with a 1:2 mixture of ether:hexane to afford the pure title compound as an oil which solidified on standing.
