No. 4,780,469) was dissolved in 80 ml dimethylacetamide (DMAC, Aldrich) at 00C and then thionyl chloride (14.2 g, 1.2 equivalent ratio, Aldrich) was gradually added to the solution. After the mixture solution was stirred for 10 min at 00C, the mixture of 8-amino-4-oxo-tetrazol-5-yl-4H- 1-benzopyran hydrochloride salt (26.7 g; 1 equivalent ratio; prepared according to the method disclosed in US Pat. No. 4,780,469) and triethylamine (TEA, 10.1 g, 1 equivalent ratio, Aldrich) dissolved in 80 ml dimethylacetamide (DMAC, Aldrich) was slowly added to the mixture solution, and thermally stirred for 5 hrs at 25C. The reaction mixture was mixed with 300 ml H2O and stirred for 1 hr at 250C. The solid material obtained by filtering the solid material produced was washed with 100 ml H2O. 200 ml 50% acetone aqueous solution was added to the solid material and then refluxed for 1 hr. After the reaction mixture was cooled to room temperature, filtered and air-dried, the mixture was kept to stand on air for 5 hrs, obtaining 47.0 g pranlukart hemihydrates (yield rate: 98%): melting point 231-233C (decomposition); 1H-NMR (DMSO-d6, 300 MHz) delta 1.9 (m, 4H), 2,7 (m, 2H), 4.0 (t, 2H), 7.0 (s, 2H), 7.1 (s, IH), 7.2-7.3 (m, 5H), 7.6 (t, IH), 7.9 (t, IH), 8.0 (m, 2H), 8.3 (t, IH), 10.0 (bs, IH).

To a suspension of the compound prepared in Example 3 (5.61 g) in methylene chloride (60 mL) were added pyridine (4.85 mL) and the previously prepared acid chloride in methylene chloride (20 mL), with ice cooling and the resulting mixture was stirred for 3 hours at room temperature. The reaction mixture was concentrated and the residue was diluted with ethyl acetate. The diluted solution was washed sequentially with water, 1N hydrochloric acid, water, saturated aqueous sodium bicarbonate solution and saturated brine, dried over anhydrous sodium sulfate and concentrated. The residue was recrystallized from a mixed solvent of ethyl acetate (100 mL) and n-hexane (100 mL) to give the title compound (8.58 g) having the following physical data. TLC: Rf 0.54 (n-hexane : ethyl acetate = 2 : 1).
