Reaction Steps

As described for example 26, 2-(4-fluoro-2-methoxy-phenyl)-5-(5-methyl-3-phenyl-isoxazol-4-yl)-[1,3,4]oxadiazole (200 mg, 0.57 mmol) was converted using 1-methylpiperidin-4-amine (195 mg, 1.71 mmol) and N,N-diisopropylethylamine (147 mg, 1.14 mmol) instead of thiomorpholine to the title compound (SiO2, heptane:ethyl acetate:dichloromethane:methanol=40:40:20:0 to 0:75:20:5, 56 mg, 22%) which was obtained as an off-white solid. MS: m/e=446.2 [M+H]+.
