Reaction Steps

To a cooled suspension (ca 0° C.) of [(3-Oxo-1,3-dihydro-isobenzofuran-1-yl)-phosphonic acid dimethyl ester] phosphonate (i) (8.0 g, 33.0 mmol) in THF (400 mL) was added crude 2-formyl-isonicotinonitrile (iid)(30.0 mmol) followed by triethylamine (6.2 mL, 33.0 mmol). The mixture was stirred for 30 minutes at 0° C. and then allowed to warm overnight.
