Reaktionsschritte

A sealed tube containing (N1-(2-(5-chloro-1H-indol-3-yl)ethyl)-N2-(2-hydroxy-1-phenylethyl)oxalamide (0.211 g, 0.546 mmol) and Burgess reagent [(methoxycarbonylsulfamoyl)triethylammonium hydroxide inner salt (0.161 g; 0.656 mmol)] in dry THF (6 mL) was stirred at 80° C. for 20 hours. The solution was evaporated and the resulting residue was purified by flash chromatography on silica gel (eluent 7 to 60% ethyl acetate in dichloromethane) to give 0.007 g (4%) of N-(2-(5-chloro-1H-indol-3-yl)ethyl)-4-phenyl-4,5-dihydrooxazole-2-carboxamide as a white solid.
