Hydrochloric Acid → HCID 59218337, compound

Participants

Reaction Steps

A solution of ethylacetoacetate (1.13 g, 8.6 mmol), 2-methoxy-6-pentadecyl benzaldehyde (3 g, 8.6 mmol) and urea (1.04 g, 17.3 mmol) in tetrahydrofuran (20 mL) was heated to reflux (65-70° C.) in the presence of hydrochloric acid (30%) for 7 h. The reaction mixture after being cooled to room temperature was poured into crushed ice (20 g) and stirred for 5 min. The viscous liquid was extracted with ethylacetate (40 mL) and was washed with 1N hydrochloric acid, water, sodium bicarbonate and brine. After drying over anhydrous sodium sulfate, the solvent was evaporated to yield light yellow oil. This crude product was purified by flash column chromatography and recrystallised from hexane to get white crystalline solid of title compound.
