Reaction Steps

Diisobutylaluminum hydride (60 ml of 1.0 M solution in hexane) was added at −65° C. to a hexane (50 ml) solution of 5-cyclopentylhexanenitrile (5.0 g; 30 mmol; from example 11). After stirring at −70° C. for 0.5 hour, and at room temperature for 3 hours, methanol (1.8 ml) was added, and the stirring continued for 20 minutes. 10% H2SO4 (48 ml) was added, and the reaction mixture was diluted with MTBE (150 ml). The organic layer was separated, washed with saturated sodium bicarbonate solution (300 ml) and brine (3×300 ml), dried (MgSO4), concentrated in vacuo, and bulb-to-bulb distilled (100° C./0.2 torr) to give 2.6 g (51.5% yield) of 5-cyclopentylhexanal.
