| Questions And Answer | Back Directory | [Synthesis]
Compound 7 (91.0 g, 0.5 mol), HCHO solution (81 g, 1.0 mol), HCl (80 g, 0.8 mol) and AcOH (200 g) were heated at 50~60 °C for 24 h to obtain a clear solution, which was then poured into cold water Chemicalbook (1kg). The resulting solid was collected by suction filtration, washed with water (60 g x 3), and dried at 50 °C to give crude cinnamon 8 (95 g) as a tan solid, which was purified by recrystallization from 90% MeOH/H2O (180 g) ) to obtain purified Meconin.
