Participants

Reaction Steps

4-[6-Methyl-2-(2,4,6-trimethylphenylamino)-pyridine-3-sulfonyl]-phenol from Example 10 (300 mg, 0.78 mmol), benzyl bromide (0.10 mL, 0.84 mmol), K2CO3 (129 mg, 0.93 mmol) and NaI (20 mg, 0.13 mmol) was heated at reflux in acetonitrile (5 mL) for 15 h. Then it was diluted with EtOAc (15 mL), filtered through florisil and the filtrate was stripped in vacuo. The residue was chromatographed on silica gel using 20% EtOAc/hexanes as eluent to give the product as a solid (340 mg), mp 158–160° C. mass spec. (AP+): m/z 473 (M+1).
