実験手順: A solution of 2-(2-methoxy-ethoxy)-phenylamine (800 mg) in DMSO (15 mL) was treated with 2,4,5-trichloropyrimidine (1.1 g) and DIEA (1.8 mL) for 16 hours. The mixture was diluted with DCM (50 mL) and washed with brine three times. The organic layer was dried over sodium sulfate and concentrated. Silica gel chromatography provided 1.0 g of (2,5-dichloro-pyrimidin-4-yl)-[2-(2-methoxy-ethoxy)-phenyl]-amine: 1H NMR (300 MHz, CDCl3) δ8.48 (d, 1H), 8.28 (bs, 1H), 8.19 (s, 1H), 7.06 (m, 2H), 6.95 (d, 1H), 4.20 (t, 2H), 3.75 (t, 2H), 3.42 (s, 3H); MS (m/e) 314 (M+1). washed with brine three times The organic layer was dried over sodium sulfate concentrated

実験手順: 2 ml of pyridine, 300 mg of N-[3-(dimethylamino)propyl]-N′-ethylcarbodiimide hydrochloride and 303 mg of 2-(2-methoxyethoxy)phenylamine are added to a solution of 250 mg of sodium [4-(morpholin-4-yl)-6-oxo-1,6-dihydropyrimidin-2-yl]acetate prepared in stage 2 of example 1, in 2 ml of N,N-dimethylformamide. The reaction mixture is stirred at ambient temperature for 15 hours, and then concentrated under reduced pressure. Water and ethyl acetate are added and the resulting mixture is thus stirred for 30 minutes. The precipitate formed is filtered off, and rinsed with water, ethyl ether and petroleum ether. The solid obtained is dried under vacuum. 223 mg of N-[2-(2-methoxyethoxy)phenyl]-2-[4-(morpholin-4-yl)-6-oxo-1,6-dihydropyrimidin-2-yl]acetamide are obtained in the form of a pinkish solid, the characteristics of which are the following: concentrated under reduced pressure Water and ethyl acetate are added the resulting mixture is thus stirred for 30 minutes The precipitate formed is filtered off rinsed with water, ethyl ether and petroleum ether The solid obtained is dried under vacuum

実験手順: 2-(2-Methoxyethoxy)-1-nitrobenzene (0.25 g, 64%) was prepared from 2-methoxyethanol (0.16 ml, 2.0 mmol) and 1-fluoro-2-nitrobenzene (0.21 ml, 2.0 mmol) following the general procedure G. This was reduced to 2-(2-methoxyethoxy)aniline (0.13 g, 60%) following general procedure B. N-[2-(2-Methoxyethoxy)phenyl]-N′-(thiazol-2-yl)urea (115 mg, 55%) was prepared from 2-(2-methoxyethoxy)aniline (115 mg, 0.7 mmol) and 2-aminothiazole (140 mg, 1.4 mmol) following the general procedure D.
