Chemistry is the experimental science by definition. We want to make observations to prove hypothesis. For this purpose, we perform experiments in the lab. 70735-79-4, Name is 4-Acetylbenzo[d]oxazol-2(3H)-one,introducing its new discovery., 70735-79-4

Synthesis of 4-acetylbenzoxazolin-2(3H)-one reported from Zea mays

A three-step alternative synthesis of 4-acetylbenzoxazolin-2(3H)-one (4) is reported. Starting from inexpensive 3-hydroxyacetophenone (1) 3-hydroxy- 2-nitroacetophenone (2) is prepared by nitration followed by catalytic hydrogenation to yield 2-amino-3-hydroxyacetophenone (3) in which a C=O unit is inserted by means of bis(trichloromethyl)carbonate (triphosgene) in the presence of triethylamine to afford 4 in 35% overall yield.
