Procedure
To a solution of diacid (Step 4) (360 mg) in dichloromethane (28 mL) and acetonitrile (7.1 mL) was added 2-chloro-1-methylpyridinium iodide (227 mg). The solution was cooled to 0 C. and triethylamine (123 μL) was added. After stirring for 15 min, 0.42 mL of a 2M solution of dimethylamine in toluene was added. The solution was stirred 1 hr at room temperature, washed with acidified 25% ammonium acetate, dried over sodium sulfate, filtered and evaporated to dryness. To the oil obtained after chromatography, in 2 mL of ethanol, was added 0.154 mL of 2N NaOH. After evaporating to dryness the title compound was obtained as a foam.
