実験手順

[2-(3-Methyl-1,2,4-oxadiazol-5-yl)phenyl]carbamoyl chloride (7.5 g) was placed in a flask equipped with an air stirrer and ground to a powder N-[2-[4-(Hydroxymethyl)-1-piperidinyl]ethyl]methanesulphonamide (9.33 g) was added and the solids intimately mixed under nitrogen for 10 min at room temperature. The mixture was stirred under a stream of nitrogen at 150° for 10 min. The mixture was allowed to cool then toluene/ethanol (10:1; 110 ml) was cautiously added followed by 8% sodium bicarbonate solution. The mixture was vigorously stirred, the layers were separated and the aqueous phase extracted with 10% ethanol in dichloromethane (4×100 ml). The organic solutions were combined and dried and concentrated in vacuo to give a beige solid. This was purified by FCC eluting with System A (100:8:1) to give the title compound (11.83 g) as fluffy off-white needles.
