Procedure

A mixture of 25 mg (0.049 mmol) of 1,2,3,4-tetrahydro-isoquinoline-6-carboxylic acid [4-(1H-imidazol-2-ylcarbamoyl)-1H-benzoimidazol-2-yl]-amide, 0.0152 mL (0.15 mmol) of benzaldehyde and 0.6 mL of DMF was stirred for 10 min. 67 mg (0.3 mmol) of sodium triacetoxyborohydride was added and the reaction mixture was stirred at room temperature for 24 h. The reaction mixture was partitioned between dichloromethane (10 mL) and water (10 mL). The organic layer was separated and dried over sodium sulfate. Purification by column chromatography on silica gel gave 11.7 mg (49%) of 2-benzyl-1,2,3,4-tetrahydro-isoquinoline-6-carboxylic acid [4-(1H-imidazol-2-ylcarbamoyl)-1H-benzoimidazol-2-yl]-amide. LCMS: 492 (M+1)+.
