Embodiment 1
[0108] Example 1: Preparation of compounds HYH11 and HYH57 (refer to the scheme shown in the following reaction formula)
[0109]
[0110] Step a: 2-Amino-6-chloropyridine (20g, 0.155mol, 1eq) was dissolved in DMF (300ml), at 0℃, N-bromosuccinimide (30.5g, 0.171mol, 1.1eq) Slowly add to the above mixture, react at room temperature for 2 hours, the reaction is complete. A large amount of water was added to precipitate a solid, filtered, washed with water, ethyl acetate / petroleum ether (V:V=1:4 (volume ratio)), and dried to obtain the crude product 2-amino-5-bromo-6-chloropyridine.
[0111] Step b: 2-Amino 5-bromo-6-chloropyridine (5.6g, 27mmol, 1eq) and N-ethylindole-5-boronic acid (5.36g, 28.3mmol, 1.05eq) were dissolved in toluene / ethanol (V :V=2:1) In the mixed solvent (75ml), add potassium carbonate (5.6g, 40.5mmol, 1.5eq) aqueous solution (56ml, 100mg potassium carbonate per ml of water) and protect with nitrogen, add tetrakistriphenylphosphonium palladium ( 1.6g, 1.35mmol,...
Embodiment 2
[0118] Example 2 Preparation of compound HYH1
[0119] It was prepared in the same manner as in Example 1, except that phenylboronic acid was substituted for 2-benzyloxy-5-fluorophenylboronic acid pinacol ester.
[0120]
