Phosphorus oxychloride → HCID 20142081, compound

Participants

Reaction Steps

2-[4-(7-Chloroquinolin-3-yloxy)phenoxy]propionamide (see Example 23) (1.2 g) was added slowly with stirring to phosphorus oxychloride (10 ml) at 20° C. The mixture was heated briefly to the boiling point then poured on to water and neutralized carefully with aqueous sodium bicarbonate solution. Extraction with ethyl acetate gave, after drying and evaporation, the crude product as a pale yellow oil. Purification by chromatography on silica gel gave 2-[4-(7-chloroquinolin-3-yloxy)phenoxy]propionitrile, characterised by its proton magnetic resonance spectrum (Table 3).
