Procedure

1-chloro-3-(4-fluorophenyl)hex-5-en-3-ol (50 mg, 0.22 mmol) and 1-methyl-1-phenylhydrazine (60 mg, 0.49 mmol) were combined and heated in a microwave for 20 min at 140° C. Starting material was still evident by LC-MS and additional 1-methyl-1-phenylhydrazine (640 mg, 5.26 mmol) was added. The mixture was further heated in a microwave for 20 min at 140° C. The crude mixture was purified by chromatography on a silica gel cartridge eluted with an EtOAc/hexanes gradient and further purified by preparative HPLC to provide 3-(4-fluorophenyl)-1-(2-methyl-2-phenylhydrazinyl)hex-5-en-3-ol (6 mg). LC-MS Method 1 m/z=315 (M+1).
