The product of Example 30 (0.444 g, 1.16 mmol) was dissolved in DMF (4 mL) and cooled to 0° C. Benzyl bromide (0.186 mL, 1.6 mmol) followed by NaH (56 mg, 1.39 mmol, 60% dispersion in mineral oil) were added and the reaction was allowed to warm to room temperature. After 1 h, the reaction was diluted with water and extracted 4× Et2O. The organics were combined, washed with brine, dried over MgSO4, concentrated in vacuo to provide 0.545 g (100%) of pure methyl 3-[Benzyl-(4-methoxy-benzenesulfonyl)-amino]-2,6-dimethoxy-isonicotinate as an oil. Electrospray Mass Spec: 472.9 (M+H)+
