Reaction Steps

600 mg (3.16 mmol) of 3-(pyridin-3-yl)-1,2-oxazole-5-carboxylic acid were initially charged in dichloromethane, and three drops of DMF were added. 1.16 g (9.15 mmol) of oxalyl chloride were added dropwise under argon (vigorous evolution of gas). The reaction solution was stirred at room temperature and then the solvent was removed on a rotary evaporator. 30 ml of toluene were added to the residue. After the toluene had been removed on a rotary evaporator, the residue was converted further directly.
