Reaction Steps

To a solution of 50 mg of 4-(4-chloro-1-oxobutyl)-α,α-dimethylphenylacetic acid, prepared in accordance with Example 4, in 3 mL of methanol is added 50 mg of NaBH4. The mixture is stirred for 30 minutes, acidified with 2N HCl, and the methanol is removed in vacuo. The concentrate is extracted with EtOAc. The organics are dried over Na2SO4, filtered, and concentrated to afford 4-(1-hydroxy-4-chlorobutyl)-α,α-dimethylphenylacetic acid.
