Reaction Steps
A solution of 2-(p-methoxybenzoyl)-3-methyl-4-hydroxy-5-chloro-7-propylbenzofuran (90 mg; 0.25 mmole), hydrazine (80 μl) and potassium hydroxide (98 mg) in ethylene glycol (2 mL) was heated at 145° C. for a period of 5 hours. The reaction mixture was cooled, poured in water, and extracted with ether. The organic phase was washed with 20% citric acid, with brine, dried (Na2SO4), and concentrated in vacuo. The residue was chromatographed on silica gel using 20% ethylacetate in hexane as eluent to yield 47 mg (50%) of 2-(p-methoxybenzyl) 3-methyl-4hydroxy-5-chloro-7-propylbenzofuran.
