Procedure

As described for example 58, 2-[2-(3-butyl-5-methyl-isoxazol-4-yl)-ethyl]-thiazole-5-carboxylic acid methyl ester (90 mg, 0.29 mmol) was converted, using L-alaninol instead of rac-2-amino-1-propanol, to the title compound (50 mg, 81%) which was obtained as a colourless oil. MS: m/e=352.4 [M+H]+.
