Reaction Steps

To (E)-1-[2-cyclopropyl-1-(2-fluorophenyl)-2-oxoethyl]-3-({1-[2-(ethoxycarbonyl)ethyl]-1H-1,2,3-triazol-5-yl}methylidene)-4-sulfanylpiperidine hydrochloride (500 mg) was added 3 N aqueous hydrochloric acid solution (20 ml) and the resulting mixture was stirred at 50° C. for 3 hours. After the reaction mixture was concentrated under reduced pressure, the residue was purified using preparative HPLC [YMC-Pack ODS-A; YMC, eluent: acetonitrile/0.024 N aqueous hydrochloric acid solution (25:75, v/v)] to afford the title compound (410 mg, yield: 87%) as a pale colourless amorphous solid.
