Benzoyl chloride → HCID 14013098, compound

Participants

Reaction Steps

To a stirred and cooled mixture of 6.2 parts of N-[2-[4-[[1-[(4-fluorophenyl)methyl]-1H-benzimidazol-2-yl]methyl]-1-piperidinyl]ethyl]-2-pyridinamine, 2 parts of N,N-diethylethanamine and 90 parts of tetrahydrofuran was added dropwise slowly a solution of 1.9 parts of benzoyl chloride in 45 parts of tetrahydrofuran. Upon completion, stirring was continued for 2 hours. The reaction mixture was evaporated. Water was added to the residue. The solution was treated with ammonium hydroxide. The product was extracted with 4-methyl-2-pentanone. The extract was dried, filtered and evaporated. The residue was crystallized from 2,2'-oxybispropane. The product was filtered off and dried, yielding 5.3 parts (69%) of N-[2-[4-[[1-[(4-fluorophenyl)methyl]-1H-benzimidazol-2-yl]methyl]-1-piperidinyl]ethyl]-N-(2-pyrimidinyl)benzamide; mp. 108.1° C. (508).
