Procedure

A solution of tetrazole (0.17 g) in dimethylformamide (2 ml) at ice-bath temperature under nitrogen was stirred with 60% sodium hydride (0.1 g) for 5 mins and then a solution of 1-hexyl-3-bromomethyl-4-methoxy-6-methyl-2(1H)-quinolinone (Example 14, 0.73 g) in dimethylformamide (8 ml) was added to it. The reaction mixture was stirred at room temperature for 2 hours, diluted with ethylacetate and then washed several times with water. The organic layer was dried and evaporated under reduced pressure. The resulting crude reaction product was chromatographed on silica-gel (30 g). Elution with 10% to 20% ethylacetatedichloromethane gave 1-hexyl-3-(1-tetrazolylmethyl)-4-methoxy-6-methyl-2(1H)-quinolinone (0.37 g). That this compound was obtained was confirmed by the spectral data: MS: m/e 355 (M+); NMR (CDCl3): δ4.18 (s, 3H, OCH3), 5.68 (s, 2H, CH2), 9,14 (s, 1H, CH= ).
