Participants

Reaction Steps

Following a procedure similar to that described in Example 134, (Z-1-[2-cyclopropyl-1-(2-fluorophenyl)-2-oxoethyl]-3-{[1-(ethoxycarbonylmethyl)-1H-imidazol-2-yl]methylidene}-4-sulfanylpiperidine hydrochloride (73.5 mg) was treated with 3N hydrochloric acid (3 ml) at 50° C. for 2 hours. The reaction solution was concentrated under reduced pressure and the residue was purified by preparative HPLC (YMC-Pack ODS-A; YMC, eluent: acetonitrile/0.024 N hydrochloric acid, 10/90, v/v) to afford the title compound (52.3 mg, yield: 95%) as a colourless amorphous solid.
