Reaction Steps

To 4-[4-(3-indolyl)piperidinomethyl]-2-(3-methoxycarbonylpropionylimino)-3-(3-methoxycarbonylpropionyl)thiazoline (700 mg) were added ethanol (25 ml) and 1N aqueous solution of sodium hydroxide (3.2 ml) and the mixture was warmed at 50° C. for 6.5 hours. To the reaction mixture was added 1N hydrochloric acid (3.2 ml) and the solvent was evaporated. After the residue was recrystallized from a mixture of ethanol and water, the crystal was collected by filtration and washed with water to give 4-[4-(3-indolyl)piperidinomethyl]-2-(3-carboxypropionylamino)thiazole (280 mg).
