Reaction Steps

A solution of 2.25 g (5.5 mm) of diethyl 1,4-dihydro-4-(2-methoxy-1-naphthalenyl)-2,6-dimethyl-3,5-pyridinedicarboxylate 20 in 12.0 mL of dry 1,2-dichloroethane was stirred under Ar at 25° C. and treated with 2.40 g (7.68 mm) of BBr3.CH3SCH3 complex. After stirring at 25° C. for 20 hours, 10.0 g of anhydrous powdered K2CO3 and 100 mL of absolute ethanol were added. Stirring was continued for 60 hours at 25°. The reaction was quenched with saturated aqueous NH4Cl and extracted with 500 ml of CH2Cl2. The organic layer was washed with pH 7 phosphate buffer and brine, dried (anhydrous Na2SO4), filtered, evaporated and flash chromatographed (silica gel, 2% acetone in CH2Cl2).
