Procedure

To the mixture containing N-(4-(2-(3-isopropylphenylamino)-1-methyl-1H-benzo[d]imidazol-5-yloxy)pyridin-2-yl)-2-(piperidin-4-yl)acetamide (1 eq), glacial acetic acid (2 eq), and formaline (7.5 eq) in tetrahydrofuran:methanol (1:1) was added sodium cyanoborohydride (2 eq) and stirred at room temperature for one hour. Reaction neutralized with saturated sodium carbonate solution and extracted with ethyl acetate. The organic layer was washed with brine, dried over sodium sulfate and concentrated to give crude product. Purification by HPLC to yield N-[4-({2-[(3-isopropylphenyl)amino]-1-methyl-1H-benzimidazol-5-yl}oxy)pyridin-2-yl]-2-(1-methylpiperidin-4-yl)acetamide.
