Procedure

To an ice-cooled mixture of lithium aluminum hydride (4 g, 105.4 mmol) in ether was added dropwise a solution of camphorsulfonyl chloride (10 g, 39.88 mmol) and ketopinic acid, prepared as described in Step 1, above. After the addition was complete, the ice bath was removed and the mixture was stirred at ambient temperature for 2 hrs. The mixture was cooled again and wet ether was added cautiously. When the violent reaction subsided, water was added. The mixture was then extracted three times with ethyl acetate. The combined extracts were washed with water and brine and dried over anhydrous magnesium sulfate. Evaporation of the solution gave 4.8 g of a white powder. NMR(δ): 0.90 (s, 3H), 1.20 (s, 3H).
