Procedure
A solution of 2.1 g of crude [2-(2-amino-3-methoxy-phenylcarbamoyl)-ethyl]-methyl-carbamic acid tert.-butyl ester in 10 mL acetic acid was heated at 65° C. for 2 h. The reaction mixture was concentrated and purified by CC with EtOAc to yield 1.5 g of [2-(7-methoxy-1H-benzoimidazol-2-yl)-ethyl]-methyl-carbamic acid tert.-butyl ester as orange foam.
