実験手順: 483 g of 2-chloro-6-methoxybenzyl bromide in 410 ml of toluene are reacted with 131 g of sodium cyanide in 132 ml of water and 3.28 g of Aliquat 336. 325 g of colorless oil are obtained (b.p. 103° C./0.08 mbar).

実験手順: 442 g of 2-chloro-6-methoxytoluene are dissolved in 2420 ml of carbon tetrachloride and, together with 516 g of N-bromosuccinimide, heated at reflux for 2 h while 5.8 g of AIBN are added. The solid is filtered off and washed with a small amount of carbon tetrachloride, the filtrate is concentrated, and the residue which remains is fractionated. 483 g of colorless oil are obtained (b.p. 100° C./1.4 mbar, m.p. 44-47° C.). heated are added The solid is filtered off washed with a small amount of carbon tetrachloride the filtrate is concentrated

実験手順: 2-(bromomethyl)-1-chloro-3-methoxybenzene (470 mg, 2 mmol), 6-methyl-2-sulfanylpyrimidin-4-ol (270 mg, 1.9 mmol), and potassium carbonate (263 mg, 1.9 mmol) were mixed in DMF (10 mL). The mixture was stirred at room temperature for 2 hours. To the mixture, water (100 mL) was added. The suspension was filtered and washed with water and ethyl acetate to provide pure titled product (400 mg, 70% yield); 1H NMR (400 MHz, DMSO-d6): δ 2.20 (s, 3H), 3.82 (s, 3H), 4.50 (s, 2H), 6.00 (s, 1H), 7.05 (m, 2H), 7.31 (t, 1H); M+297. The suspension was filtered washed with water and ethyl acetate

実験手順: In a 250 mL round bottom flask, 1-chloro-3-methoxy-2-methylbenzene (5.0 g, 31.9 mmol) was dissolved in CCl4 (50 mL). To the solution, 1-bromopyrrolidine-2,5-dione (5.8 g, 32.6 mmol) and benzoyl benzenecarboperoxoate (70 mg) were added in sequence. The resulting mixture was refluxed for 4 hours and left at room temperature overnight. The mixture was filtered. The filtrate was evaporated to provide crude product of 2-(bromomethyl)-1-chloro-3-methoxybenzene as a colorless liquid, which was used for next step without further purification. The resulting mixture was refluxed for 4 hours The mixture was filtered The filtrate was evaporated
