Reaction Steps

Prepared analogously to Example 1f from 3-chloro-4-(tetrahydro-pyrimidin-2-on-1-yl)-benzoic acid, (1S)-1-(5-chloro-1H-benzimidazol-2-yl)-ethylamine, TBTU and NMM in DMF, then pouring into ice water, adding conc. ammonia solution, filtering, washing with water and purifying by chromatography on silica gel (eluting gradient ethyl acetate/(methanol/conc. ammonia solution 19:1)=98:2→90:10) with subsequent filtration through activated charcoal, trituration with ether and drying in the drying pistol at 70° C.
