Reaction Steps
200 mg of the peptide obtained in Example I is introduced into 5 ml water after which 0.025 ml 0.5 M ammonium molybdate, 0.125 ml HClO4 and 0.075 ml 30% hydrogen peroxide are added. The mixture is stirred for about 4 hours at room temperature, after which 5 ml tert. butanol/water (1:1) and an ion exchange resin in acetate form are added. After stirring for about 30 minutes, the ion exchange resin is separated by filtration and the filtrate is evaporated to dryness.
