(i) Preparation of 2-bromo-3-chloro-5-methylpyridine The product from paragraph (h) (5.7 g) in hydrobromic acid (48%; 50 ml) was cooled to -15 C. to -10 C. and bromine (2.6 ml) was added dropwise with stirring. The temperature was then kept at -5 C. to 0 C. while sodium nitrite (5.53 g) in water (12 ml) was added dropwise over a period of 45 minutes. When addition was complete, the mixture was stirred a further 30 minutes at 0 C. and poured on to ice. The mixture was made slightly alkaline by dropwise addition of concentrated ammonia, keeping the temperature at 0 C. with added ice. The mixture was extracted with ether (150 ml). The ether extract was washed with water, sodium bisulphite solution, and water, and then dried and evaporated. The residue was taken up in petroleum (b.p. 40-60 C.) and the solution filtered and evaporated. The residue was identified as 2-bromo-3-chloro-5-methylpyridine. |

With tris-(dibenzylideneacetone)dipalladium(0); 2,2'-bis-(diphenylphosphino)-1,1'-binaphthyl; sodium t-butanolate; In toluene; at 90.0℃; for 18.0h; | 10225] WXO14-1 (500.00 mg, 2.42 mmol, 1.00 eq) and compound WX1313-3-1 (533.51 mg, 2.66 mmol, 1.10 eq) were dissolved in methylbenzene (25 ml). Tris(dibenzylideneacetone)dipalladium (221.76 mg, 242.00 tmol, 0.10 eq), sodium tert-butoxide (349.08 mg,3.63 mmol,1.50 eq) and binaphthyl (I3INAP) (301.37 mg, 484.00 tmol, 0.20 eq) were added. The mixture was reacted at 90 C. for 18 h. Afier reaction, the reaction liquid was filtered through diatomite, the filtrate was washed with ethyl acetate (10 ml), and dried by rotary evaporation under vacuum. Ethyl acetate (50 ml) was added to residue. The resulting mixture was washed with water (10 ml), the organic phase was dried by rotary evaporation under vacuum, and the crude was purified by column chromatography (petroleum ether:ethyl acetate=30:1-10:1) to obtain the compound WXO14-2. ?H NMR (400 MHz, CDC13) oeppm: 7.76 (s, 1H), 7.22 (s, 1H), 4.79 (d, J=4.00 Hz, 1H), 3.98 (br, s, 1H), 3.30 (br, s, 3H),2.09 (s, 3H), 1.87-1.82 (m, 2H), 1.65-1.58 (m, 3H), 1.33 (s, 9H). |
