Reaction Steps

A suspension of 6-(1,2,4-triazol-1-yl)-8-methyl-2-(1H)-quinolone (see Example 9) (1.7g) in ethanol (450 cm3) was hydrogenated at 60° and 60 p.s.i. (4.13×105Pa) pressure over 10% palladised charcoal (0.35g) for 72 hours. The cooled mixture waas then filtered through "Solkafloc" (Trademark for a cellulose based filtering agent) and evaporated in vacuo to afford a solid. Chromatography on silica (Merck "MK 60.9385" [Trade Mark]) eluting with chloroform: methanol, 49:1, followed by combination and evaporation of the appropriate fractions in vacuo gave a solid which was recrystallised from ethyl acetate/methanol to give 3,4-dihydro-8-methyl-6-(1,2,4-triazol-1-yl)-2-(1H)-quinolone, m.p. 258°-259° (0.266 g).
