Procedure

As described for example 95, 2-[(E)-2-(3-butyl-5-methyl-isoxazol-4-yl)-vinyl]-4-methyl-thiazole-5-carboxylic acid methyl ester (60 mg, 0.19 mmol) was converted, using rac-2-amino-1-propanol instead of isopropylamine, to the title compound (45 mg, 79%) which was obtained as a colourless oil. MS: m/e=364.1 [M+H]+.
