Participants

Reaction Steps

Aqueous sodium hydroxide (2M, 0.5 ml) is added to a stirred solution of {3-[5-(4-methanesulfonyl-phenyl)-4-methyl-thiazol-2-yl]-ureido}-acetic acid ethyl ester (Example 60) (0.14 g, 0.00035 mmol) in methanol (2 ml). After stirring at room temperature for 18 hours the solvent is removed and dilute HCl is added. The resulting yellow solid is removed by filtration and recrystallised from ethanol to afford the title compound. MH+ 370.0
