الإجراء التجريبي

Under nitrogen atmosphere, a dimethyl sulfoxide (3 ml) solution of (3R)-3-methylaminopyrrolidine (95 μl, 0.88 mmol) was added at 150° C. to a dimethyl sulfoxide (17 ml) solution of 4-cyano-7-fluoro-N,N,5-trimethyl-6-phenyl-1,3-benzoxazole-2-carboxamide (I-114) (271 mg, 0.838 mmol) and triethylamine (156 μl, 1.09 mmol), followed by stirring at the same temperature for 30 minutes. After cooling, saturated brine was added to the reaction liquid, and the reaction liquid was extracted with chloroform.
