反応手順

A solution of the methyl5-[3-amino-4-(methylamino)phenoxy]pyridine-3-carboxylate (1 eq) in methanol (8 ml) was treated with 4-bromophenylisothiocyanate (1 eq) and stirred at 60° C.-65° C. for 2 hours. The reaction mixture was cooled down to room temperature and methyl iodide (1 eq) was added and stirred overnight at 60° C. The reaction was cooled down to room temperature, evaporated, taken up in ethyl acetate and washed with water and brine, dried, evaporated under reduced pressure. Column chromatography yielded methyl5-{2-[(4-bromophenyl)amino]-1-methylbenzimidazol-5-yloxy}pyridine-3-carboxylate. MS: MH+=452
