Reaction Steps

A sealed tube containing (S)—N1-(2-(5-chloro-1H-indol-3-yl)ethyl)-N2-(1-hydroxy-3-phenylpropan-2-yl)oxalamide (0.117 g, 0.293 mmol) and Burgess reagent [(methoxycarbonylsulfamoyl)triethylammonium hydroxide inner salt (0.115 g; 0.468 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 0.005 g (4%) of (S)-4-benzyl-N-(2-(5-chloro-1H-indol-3-yl)ethyl)-4,5-dihydrooxazole-2-carboxamide as a white solid.
