A mixture of 21.7 mg (0.08 mmol) (1H-indol-5-yl)-(4-isopropyl-piperazin-1-yl)-methanone (intermediate 1), 16 mg (0.16 mmol) cyclopentylmethynol (commercially available), 38.6 mg (0.16 mmol) cyanomethylenetri-n-butylphospborane in toluene was heated to 110° C. for an extended period of time. After evaporation the residue was purified by preparative HPLC on reversed phase eluting with a gradient formed from acetonitrile/water/NEt3. The combined product fractions were evaporated to yield 5.4 mg of the title compound. MS (m/e): 354.4 (MH+).
