In a similar way to that described in Example 30, 7-fluoro-1-methyl-3-(1-methyl-1H-tetrazol-5-yl)-4-quinolone (5 g) was boiled under reflux with pyrrolidine (50 ml) for 20 hours to give 1-methyl-3-(1-methyl-1H-tetrazol-5-yl)-7-pyrrolidino-4-quinolone, m.p. 267°-270° (from industrial methylated spirit:water 5:1).
