Versuchsvorschrift

To a stirred solution of methyl 5-bromo-3-(((trans)-4-((tert-butoxycarbonyl)amino)cyclohexyl)(ethyl)amino)-2-methylbenzoate (3 g, 6.41 mmol, see, e.g., WO2012142504) in THF (30 mL), NaH (0.184 g, 7.69 mmol) was added at 0° C. and stirred it at same temperature for 20 min. Then methyl iodide (9.10 g, 64.10 mmol) was added at 0° C. and reaction was stirred for overnight at room temperature. On completion, reaction was quenched with ice water and extracted with dichloromethane. The combined organic layers were washed with water, dried, concentrated under reduced pressure. The crude compound was purified by column chromatography to afford the crude title compound that was used without further purification (3 g, 97.4% yield).
