Participants

Reaction Steps

N-(trans-4-Amino-cyclohexyl)-5-fluoro-2-(3-methylsulfanyl-phenoxy)-nicotinamide hydrochloride (400 mg, 1.065 mmol) was dissolved in dichloromethane (6 ml) and triethylamine (445 μl, 3.20 mmol) was added followed by dropwise addition of 5-chlorovaleryl chloride (151 μl, 1.172 mmol). The reaction was stirred under nitrogen at room temperature for 4 h. The reaction mixture was quenched with sat. sodium hydrogen carbonate solution (10 ml) and extracted with dichloromethane (3×15 ml). The combined organic extracts were dried over MgSO4 and the solvent was removed under reduced pressure. The residue was purified by column chromatography, eluting with 95:5 dichloromethane/methanol, clean fractions were combined and the solvent was removed under reduced pressure to obtain the title compound (220 mg) as a white solid.
