Reaction Steps

To 4-amino-2-methylphenol (5.0 g, 40.6 mmol) was added 6M HCl (100 mL) and heated to 100° C. with stirring. Toluene (30 mL) was added followed with the slowly addition of crotonaldehyde (6.7 mL, 81.2 mmol) at 100° C. The mixture was stirred at 100° C. for 2 hours, cooled to room temperature. The water layer was separated, neutralized by NaHCO3 solution. The solid formed was filtered and collected. LCMS-ESI+: calc'd for C11H11NO: 174.1 (M+H+); Found: 174.2 (M+H+).
