As a common heterocyclic compound, it belongs to benzoxazole compound, name is Benzo[d]oxazol-6-amine, and cas is 177492-52-3, its synthesis route is as follows.

A mixture of 5-amino-3-(trifluoromethyl)picolinonitrile (Intermediate 1 , 110 mg, 0.59 mmol), benzo[d]oxazol-6-amine (Intermediate 79, 125 mg, 0.59 mmol), and thiophosgene (0.05 mL, 0.60 mmol) in anhydrous DMA (3 mL) was stirred at 60C for 16h. Methanol (3 mL) and 2M HC1 (1.5 mL) were then added and the mixture was heated at 90C for 2h. The reaction mixture was cooled and poured into ice/water (40 mL) and the resultant solid was filtered to afford 150 mg of 5-(5-(4-amino-3-hydroxyphenyl)-8-oxo-6-thioxo-5,7-diazaspiro[3.4]octan-7- yl)-3-(trifluoromethyl)picolinonitrile as a brown powder. LCMS [M + 1]+ 434.0.
