Reaction Steps

7-methyl-5-(pyridin-3-yl)-3-(2,2,2-trifluoroethyl)-3H-pyrrolo[2,3-d]pyrimidin-4(7H)-one (0.28 g, 0.908 mmol) was dissolved in DMF (8 ml). The solution was cooled down to 0° C. Bromine (0.056 ml, 1.09 mmol) was added in dropwise. After 30 min, the reaction mixture was diluted with a aqueous mixture (3:1:4 water, saturated sodium bicarbonate solution and 20% w/w sodium thiosulfate solution, 80 ml) and extracted with ethyl acetate (3×50 ml). The combined organic phase was washed with water (4×60 ml), brine and concentrated to give title compound (0.13 g, 37%). LCMS RT=0.81 min, [M+H+(79Br)]=387.0, [M+H+(81Br)]=389.0.
