In the chemical reaction process, reaction time, type of solvent, can easily affect the result of the reaction, thereby determining the yield and properties of the reaction product. An updated downstream synthesis route of 124750-92-1 as follows. Computed Properties of C22H21ClN6O2

To a 100 ml of one-necked flask, 4.36 g of 2-butyl-4-chloro-1-[2′-(1H-tetrazol-5-yl)1,1′-biphenyl-methyl]imidazole-5-carboxylic acid, 15 ml of N,N-dimethylformamide, 1.66 g of potassium carbonate and 2.78 g of triphenylchloromethane were added in turn. The mixture was reacted at room temperature overnight. The reaction was stopped and 100 ml of water was added. The resulting mixture was extracted with 100 ml of ethyl acetate and washed once by saturated brine. The organic phase was dried and concentrated to give 7.5 g of 2-butyl-4-chloro-1-[2′-(1-triphenylmethyl-tetrazol-5-yl) 1,1′-biphenyl-methyl]-imidazole-5-carboxylic acid as a yellow oil. The crude product obtained from this example was used as material referred to in the following examples without purification.
