Procedure

As described for example 57b, 2-[2-(3-butyl-5-methyl-isoxazol-4-yl)-ethyl]-thiazole-5-carboxylic acid methyl ester (90 mg, 0.29 mmol) was converted, using tetrahydrofuran-3-amine instead of isopropylamine, to the title compound (45 mg, 71%) which was obtained as a light yellow oil. MS: m/e=364.3 [M+H]+.
