実験手順
As described for example 104, 2-[(E)-2-(3-butyl-5-methyl-isoxazol-4-yl)-vinyl]-4-methyl-thiazole-5-carboxylic acid (153 mg, 0.5 mmol) was converted, using L-2,2,2,-trifluoro-1-(methyl)ethylamine instead of rac-2-amino-1-butanol, to the title compound (92 mg, 46%) which was obtained as a white solid after purification by chromatography (silica, 50 to 100% ethyl acetate in heptane and recrystallization from ethyl acetate/heptane. MS: m/e=402.3 [M+H]+.
