Procedure

To a suspension of diacid (Example 25) (0.3 g) in dichloromethane (20 mL), acetonitrile (5 mL) and triethylamine (200 μL) was added 2-chloro-1-methylpyridinium iodide (180 mg). The mixture was stirred 30 min, cooled to 0° and 0.32 mL of a 2M solution of dimethylamine in toluene was added. The reaction was stirred 2 hours at room temperature. The reaction mixture was poured onto NH4OAc buffer and acetic acid (5 mL) was added. The mixture was extracted with ethyl acetate, which was dried over sodium sulfate and evaporated. Purification of the residue by flash chromatography starting with 15% and finishing with 30% of THF in toluene containing 1% of acetic acid afforded the title compound.
