70% With sodium t-butanolate; In N,N-dimethyl-formamide; at 20℃; for 24h; Synthesis of intermediate compound 4[00107] In a 300 ml eggplant-type flask, 7.00 g (31.4 mmol) of compound 3, 3.30 g (34.5 mmol) of sodium tert-butoxide, and 100 ml of DMF were placed. Then, 2.15 ml (34.5 mmol) of idomethane was added dropwise to the resultant mixture, followed by stirring at room temperature for 24 hours. The loss of the raw materials and production of a new compound were confirmed by TLC (Thin Layer Chromatography) . The reaction solution was concentrated, and an organic phase was recovered by three times of separation with toluene/water. The organic phase was dried over magnesium sulfate,concentrated, and then purified by silica gel columnchromatography (developing solvent toluene : heptane : ethyl acetate = 10:10:1). A target substance was concentrated to produce 5.21 g (22.0 mmol) of compound 4 (yield 70.0%).Nine protons were attributed by 1H-NMR (CDC13: 7.95 (s, 1H) , 7.71 ppm (d, 1H) , 7.42-7.39 ppm (m, 2H) , 7.26 ppm (t, 1H) , 6.53 ppm (d, 1H) , 3.96 ppm (s, 3H) ) . A peak was observed at m/z = 236 in GS-MS (gas chromatography direct-coupled to mass spectrometry) to confirm the target compound.

Thereto, 2.15 ml (34.5 mmol) of iodomethane was added dropwise and the mixture was stirred for 24 hours at room temperature. Elimination of the raw materials and generation of a new compound were confirmed by thin layer chromatography (TLC).

The organic phase was dried over magnesium sulfate, concentrated, and purified by silica gel column chromatography (developing solvent:toluene: heptane: ethyl acetate = 10:10:1). The target substance was concentrated to obtain 5.21 g (22.0 mmol) of compound 4 (yield: 70.0%). Nine protons were assigned by 1H- NMR (CDCl3:7.95 (s, 1H) , 7.71 ppm (d, 1H) , 7.42-7.39 ppm (m, 2H), 7.26 ppm (t, 1H) , 6.53 ppm (d, 1H) , 3.96 ppm (s, 3H) ) . When analyzed with a gas chromatograph-mass spectrometer (GS-MS), a peak was observed at m/z = 236. The product was confirmed to be the target substance.
