関与物質

反応手順

Nitric acid (70%) (15.6 g, 185 mmol) was added slowly to a solution of 1,3-di-iso-propyl-benzene (available from Aldrich) (20 g, 123 mmol) in acetic acid (50 mL) and acetic anhydride (50 mL) at 0° C. over 20 min. After stirring at room temperature for 1 hour, the reaction mixture was diluted with water (250 mL) and hexane (500 mL). The organic layer was then washed with with water (50 mL), saturated Na2CO3 (50 mL), dried (Na2SO4) and concentrated to give the title compound in a crude form (25 g, 98% yield) as a colorless oil:
