Reaction Steps

0.96 g rac-2-propoxy-3-[1-(2-trimethylsilanyl-ethoxymethyl)-1H-indol-5-yl]-propionic acid were dissolved in 40 ml N,N-dimethylformamide. 0.94 ml Ethylene diamine were added, followed by 7.63 ml of a tetra-butylammonium fluoride solution (1 molar in tetrahydrofuran); a small amount of molecular sieves was then added to the reaction mixture and it was heated to 80° C. After 6 hours, the mixture was cooled to r.t., filtered and the filtrate was poured into ice water and extracted 3 times with dichloromethane. The organic phases were washed with water, dried over MgSO4, filtered again and evaporated. The crude rac-3-(1H-indol-5-yl)-2-propoxy-propionic acid was used for the next step without purification.
