The downstream synthesis method of this compound is introduced below.

Intermediate 1 To a solution of 4-fluoro-2-methyl-lH-indol-5-ol (200 mg, 1.21 mmol) in a mixture of acetonitrile (4 mL) and N, N-dimethylformamide (1 mL) was added potassium carbonate (200 mg, 1.45 mmol). The reaction mixture was stirred for lh at room temperature before a suspension of 4, 6-dichloropyrimidine-5-carbonitrile (221 mg, 1.27 mmol) in 3 mL of acetonitrile was added. This mixture was stirred at room temperature for 1 h. TLC was checked and the reaction was completed. The mixture was diluted with water and ethyl acetate. The layers were separated and the aqueous phase was extracted twice with ethyl acetate. The combined organic phases were washed once with water, then with brine, dried over sodium sulfate, filtered, and the filtrate was concentrated in vacuo to give the desired product as brown solids (365 mg, 99% yield). 1H MR (400 MHz, DMSO-d6) delta 11.46 (br, 1H), 8.83 (s, 1H), 7.17 (d, J = 8.8 Hz, 1H), 7.00 (t, J = 7.6 Hz, 1H), 6.27 (s, 1H), 2.41 (s, 3H); ESI-MS: calcd for (C14H8C1FN40) 302, found 303 (MH+).

According to the analysis of related databases, 5305-45-3, the application of this compound in the production field has become more and more popular.
