Participants

Reaction Steps

To a solution of (6-amino-5-((5-(3-fluoro-phenoxy)-thiophen-2-ylmethyl)-carbamoyl)-pyridine-2-yl)-carbamic acid tert-butyl ester described in Preparation Example A+-2 (125 mg, 0.27 mmol) and methyl iodide (43 mg, 0.29 mmol) in N,N-dimethylformamide (5 mL) was added sodium hydride (12 mg, 0.29 mmol, 60% in oil) on an ice bath, and the solution was stirred for 1 hour at room temperature. NH silica gel was added to the reaction solution, the solvent was evaporated in vacuo for adsorption, purification was carried out by NH silica gel column chromatography (hexane:ethyl acetate=4:1 then 2:1), and the title compound (87 mg, 0.19 mmol, 70.5%) was obtained as a colorless oil.
