Participants

Conditions

Temperature: 45 °C

Procedure

A mixture of 200 mg (0.373 mmol) N-(3,5-bis-trifluoromethyl-benzyl)-N-methyl-6-piperazin-1-yl-4-o-tolyl-nicotinamide (Example 53), 66 mg (0.56 mmol) 3-(chloromethyl)-1,2,4-oxadiazole and 62 mg (0.45 mmol) potassium carbonate in 4 ml acetonitrile was stirred at 45° C. for 1 h and at room temperature over night. The reaction mixture was diluted with 10 ml water and extracted with 3 30-ml portions of dichloromethane. Drying with sodium sulfate and concentration gave 244 mg of the crude product. Flash column chromatography afforded 80 mg (34.7%) of the title compound as a red-brown solid.
