실험 절차

A mixture of 4-aminophenol (1 g, 9.17 mmol) and magnesium sulfate (4 g) in 2-hydroxy-2-methylpropanenitrile (10 mL) was heated to 80° C. for 2 h. Ice/water was added to a cooled mixture and it was stirred for 30 min. The white solid that precipitated was filtered, washed with water, and dried to afford 1.2 g (74%) of 2-((4-hydroxyphenyl)amino)-2-methylpropanenitrile as a white solid. 1H NMR (400 MHz, CDCl3) δ 8.89 (s, 1H), 6.78 (d, 2H), 6.65 (d, 2H), 5.21 (s, 1H), 1.52 (s, 6H).
