Propargyl alcohol → N-cyclohexylmethyl-4-(2-propynyloxy)-3,5-difluorobenzamide

Participants

Reaction Steps

To 10 ml of DMF were added 0.50 g of N-cyclohexylmethyl-3,4,5-trifluorobenzamide and 0.15 g of propargyl alcohol and to the mixture obtained was added 100 mg of sodium hydride at 0° C. The mixture obtained was stirred at room temperature for 2 hours. Then, the reaction mixture was concentrated. The residue was subjected to silica gel column chromatography to obtain 0.49 g of N-cyclohexylmethyl-4-(2-propynyloxy)-3,5-difluorobenzamide (hereinafter, described as the compound 32 of the present invention) represented by the formula:
