Procedure:
In an apparatus similar to Example 1, 15.0 g (0.099 mol) of vanillin and 10.0 g (0.072 mol) of anhydrous potassium carbonate were heated under nitrogen to 90° C. To this clear slurry was added over about 10 minutes 13.5 ml (0.112 mol) of trimethyl phosphate while holding the temperature below 110° C. The mixture was stirred and heated to 65°-75° C. for three hours then cooled to 35° C. and quenched with 80 ml of water to precipitate an oil. On stirring a light powder precipitated which was filtered, washed with three 100 ml portions of water, and dried to give 13.3 g (81%) of veratraldehyde.

Procedure:
To 2-bromo-4-fluoro-1-nitrobenzene (185.16 mg, 0.842 mmol) was added Pd2dba3 (23.12 mg, 0.025 mmol) and copper powder (271 mg, 4.26 mmol). Dimethylsulfoxide (2.3 ml) and methyl 2-bromo-4-fluorobenzoate (0.122 ml, 0.842 mmol) were added and the mixture was stirred vigorously at 100° C. for 2 h. The mixture was cooled to room temperature, diluted with ethyl acetate (20 ml), and filtered. The filtrate was washed with water and dried (anhydrous Na2SO4) and concentrated to give a yellow oil (279.8 mg). This oil was utilized without purification for the preparation of Example 38b.

A solution of triphenylphosphine (1.5 eq) in dichloromethane is treated dropwise with diethyl azodicarboxylate (1.5 eq) at 25° C. The solution is allowed to stir for 10 min followed by the dropwise addition of a solution containing the product of Example 436 (1 eq) and n-propanol (1.1 eq) in dichloromethane. The resulting solution is stirred at 25° C. for 20 hours, followed by the addition of dichloromethane and 1N aqueous hydrochloric acid. The resulting organic layer is separated and dried over magnesium sulfate, and filtered to provide the title compound.
