Crystalline 4'-[(1,4'-dimethyl-2'-propyl[2,6'-bi-1H-benzimidazol]-

1'-yl)methyl]-[1,1'-biphenyl]-2-carboxylic acid methyl ester

4'-[(1,4'-dimethyl-2'-propyl[2,6'-bi-1H-benzimidazol]-1'-yl)methyl]-[1,1'-biphenyl]-2- carboxylic acid methyl ester is used as intermediate in the preparation of (4'-[(1,4'- dimethyl-2'-propyl[2,6'-bi-1H-benzimidazol]-1'-yl)methyl]-[1,1'-biphenyl]-2-carboxylic acid). Its chemical formula is:

4'-[(1,4'-dimethyl-2'-propyl[2,6'-bi-1H-benzimidazol]-1'-yl)methyl]-[1,1'-biphenyl]-2- carboxylic acid methyl ester was supplied by Sinochem and was analyzed by X-Ray powder diffraction.

Main XRD peaks in figure 1 are: 7.8, 12.2, 13.7, 15.3, 18.9, 20.4, 20.9, 22.5, 23.5 and
25.4 (±0.2 two-theta).
