Participants

Reaction Steps

3-(methoxycarbonyl)-5-methylisoxazole-4-carboxylic acid (1 mmol) was dissolved in N,N-dimethylformamide (5 ml), then diisopropylethylamine (1.2 eq.) and TBTU (1.2 eq) was added and stirred at room temperature for 5 minutes. 1-(3-fluorobenzyl)-3-(4-((methylamino)methyl)thiazol-2-yl)urea (1.0 mmol) was added and stirred overnight. Water (20 ml) was added to the reaction. The precipitate was filtered, washed with water and dried. The crude was purified by column using 0-100% gradient of 10% MeOH/EtOAc and hexanes to afford methyl 4-(((2-(3-(3-fluorobenzyl)ureido)thiazol-4-yl)methyl)(methyl)carbamoyl)-5-methylisoxazole-3-carboxylate.
