The invention provides 6-bromo-3-methoxy-1-phenyl-1H-indazole as well as a synthesis method and application thereof, and the synthesis method comprises the following steps: taking 6-bromoindazole as a raw material, and reacting with nitrate in a first organic solvent; the obtained 6-bromo-3-nitro-1H-indazole and sodium methoxide are subjected to a reaction in a second organic solvent; and then the obtained 6-bromine-3-methoxy-1H-indazole reacts with phenyl halide in a third organic solvent in the presence of alkali, a ligand and copper iodide, and the 6-bromine-3-methoxy-1H-indazole is obtained. According to the invention, the 6-bromo-3-methoxy-1-phenyl-1H-indazole is synthesized by adopting three steps, so that tedious reaction operation and use of expensive, high-toxicity and high-risk reagents in the prior art are avoided, and the method is a simple, feasible, green and environment-friendly synthesis method. In addition, raw materials and auxiliary materials used in the synthesis method are cheap and easy to obtain, reaction conditions are mild, operation is easy and convenient, the process is stable, the whole synthesis process is high in controllability, aftertreatment is simple, and the method is suitable for large-scale production.

GPR120 agonists have therapeutic potential for the treatment of diabetes, but few selective agonists have been reported. We identified an indazole-6-phenylcyclopropylcarboxylic acid series of GPR120 agonists and conducted SAR studies to optimize GPR120 potency. Furthermore, we identified a (S,S)-cyclopropylcarboxylic acid structural motif which gave selectivity against GPR40. Good oral exposure was obtained with some compounds displaying unexpected high CNS penetration. Increased MDCK efflux was utilized to identify compounds such as 33 with lower CNS penetration, and activity in oral glucose tolerance studies was demonstrated. Differential activity was observed in GPR120 null and wild-type mice indicating that this effect operates through a mechanism involving GPR120 agonism.
