Reaction Steps
A solution of triphenylphosphine (39.3 g, 150 mmol) in tetrahydrofuran (600 ml) was treated at 0° C. with bis(1-methylethyl) (E)-1,2-diazenedicarboxylate (30 ml, 152 mmol). After 10 minutes [5-({[4-(methoxy)phenyl]methyl}oxy)-4-oxo-1,4-dihydro-2-pyridinyl]methyl acetate (33.5 g, 110 mmol) (for a synthesis, see WO2004058144, Example 60(c)) was added. After 10 minutes benzyl alcohol (12.4 ml, 120 mmol) was added and the mixture was stirred overnight. Evaporation and chromatography on silica eluting with 20-50% ethyl acetate in hexane afforded an oil (26.3 g, 61%).
