実験手順
Combine 1-(2-aminoethyl)-2-imidazolone (100 g, 774 mmol) with 4-(7-bromo-benzo[b]thiophen-2-yl)-2-chloro-5-fluoro-pyrimidine (90 g, 262 mmol) in 1,4-dioxane (650 mL) and heat to 90° C. with stirring under nitrogen for 3 hours. Cool the reaction to room temperature. Filter and wash the solid with water (3×500 mL) and diethyl ether (500 mL). Vacuum-dry at 50° C. to give the title compound (59.2 g, 52%) as a yellow solid. MS (ES) m/z 436 [M+1]+.
