Reaction Steps

(S)-2-(1-((6-Amino-5-iodopyrimidin-4-yl)amino)ethyl)-5-methyl-3-phenylpyrrolo[2,1-f][1,2,4]triazin-4(3H)-one (220 mg, 0.45 mmol) and methyl 3-fluoro-4-methoxybenzenethiol (107 mg, 0.68 mmol) were dissolved in 10 mL dimethylformamide in a microwave vessel. Potassium carbonate (94 mg, 0.68 mmol) and copper(I) iodide (129 mg, 0.68 mmol) were added and the mixture was heated overnight at 70° C. The reaction mixture was cooled at room temperature and diluted with ethyl acetate. The organic phase was washed with 2N HCl, 4% sodium bicarbonate solution, water and brine and dried over sodium sulphate, filtered and evaporated under reduced pressure. The residue (0.26 g, 87%) was used in the next synthetic step without further purification. Purity 78%.
