実験手順

0.559 g (1 mmol) of (2S)-2-(1-adamantylmethoxycarbonylamino)-3-((5-(2-(1,4,5,6-tetrahydropyrimidin-2-ylcarbamoyl)-ethyl)-thiophene-2-carbonyl)-amino)-propionic acid (example 15) were dissolved in 10 ml of isopropanol. Under an inert gas atmosphere and under external cooling 0.26 ml of thionyl chloride were cautiously addded. After stirring for 8 hours at 50° C. the reaction was complete. The solvents were removed in vacuo to give a colourless foam which was purified by chromatography (silica gel; isopropanol/ethyl acetate/water (4/3/1; v/v/v)). The fractions containing the title compound were lyopholized to give 0.27 g of a colourless fluffy material.
