Procedure

To a mixture of 4-methyl-2-tritylamino-5-thiazolecarboxylic acid (7.2 g) and 2-(3,4-dimethoxyphenyl)ethylamine (3.26 g) in N,N-dimethylformamide (100 ml) were added 1-hydroxybenzotriazole (2.92 g) and dicyclohexylcarbodiimide (4.45 g) and the mixture was stirred at ambient temperature for 1 hour. After filtration, the filtrate was evaporated under reduced pressure. The residue was dissolved in chloroform-methanol (9:1 v/v, 20 ml), removed undissolved materials by filtration, and the filtrate was subjected to column chromatography on silica gel to give N-[2-(3,4-dimethoxyphenyl)ethyl]-4-methyl-2-tritylamino-5-thiazolecarboxamide (8.65 g).
