Reaction Steps

Borane-tetrahydrofuran (1.0M in tetrahydrofuran, 1.5 mL, 0.0016 mole) was added by syringe to a solution of 2-butoxy-6-(4-fluorophenyl)-5-[4-(methylsulfonyl)phenyl]pyridine-3-carbonitrile (Example 14) (0.68 g, 0.0016 mole) in tetrahydrofuran (100 mL). After stirring at room temperature for 1 hour the solution was heated to reflux for 20 hours. Additional borane-tetrahydrofuran (2.4 mL) was added in three portions over the next 3 hours to the hot solution and stirred for 1 hour before cooling to room temperature. Methanol (20 mL) was added and the solution was concentrated to an oily solid. The product was purified by silica gel chromatography. Anal. Calc. C23H25N2 O3SF·0.5M H2O: C, 63.14; H, 5.99; N, 6.40. Found: C, 63.31; H, 5.94; N, 6.29.
