To a mixture of 2-(1-(tert-butoxycarbonyl)piperidin-4-yl)acetic acid (1 eq) in N,N-dimethyl formamide and N,N,disopropylethylamine (4 eq) was added HATU (2 eq) and the mixture was stirred at ambient temperature until it becomes homogeneous. To it was added 5-(2-aminopyridin-4-yloxy)-N-(3-isopropylphenyl)-1-methyl-1H-benzo[d]imidazol-2-amine (1 eq) and 4-(dimethylamino)pyridine (0.05 eq) and the resulting mixture was stirred at room temperature for 16 h. The reaction mixture was then concentrated and partitioned between ethyl acetate and water. The organic layer was dried over sodium sulfate and the resulting tert-butyl 4-((4-(4-(methylamino)-3-nitrophenoxy)pyridin-2-ylcarbamoyl)methyl)piperidine-1-carboxylate was purified by HPLC. HPLC=4.63 min; MS: MH+=599.
