Procedure
A mixture of 5-fluoro-2-hydroxyacetophenone on Wang resin (4.0 g, 4.6 mmol) was swelled in trimethyl orthoformate (40 mL) for 10 min. 25% NaOMe in MeOH (2.0 g, 9.2 mmol) was added and the mixture was stirred for 45 min. Cyclohexanecarboxaldehyde (1.5 g, 13.8 mmol) was added and stirring was continued for 40 min. The resin was filtered and washed with alternating MeOH and CH2Cl2 (×5) and dried under high vacuum overnight to give 4.3 g of 3-cyclohexyl-1-(2-hydroxy-5-fluorophenyl)-2-propen-1-one on Wang resin.
