Reaction Steps
A mixture of 2-hydroxy-3-methoxy-benzaldehyde (10 g, 6.57 mmoles), K2CO3 (18.16 g, 131 mmoles), cyclopentyl-bromide (14.05 ml, 131 mmoles) in absolute ethanol (150 ml) under nitrogen was refluxed under stirring for 55 hours. The mixture was diluted with water, thrice extracted in ethyl acetate, washed with water, anhydrified over Na2SO4 and evaporated to dryness, the yielded oil was purified by flash chromatography on silica gel (eluent petrolatum/ethyl acetate 95:5) to give 8.9 g of the title product (yield: 61%).
