Participants

Reaction Steps

A solution of 4-(cyclopropylmethyl-amino)-benzenesulfonic acid 2-methoxycarbonylamino-3H-benzoimidazol-5-yl ester (example 67, 40 mg) and 2-(aminoethyl)-morpholine (125 mg) in tetrahydrofuran (2 ml) and N-methylpyrrolidinone (0.2 ml) was heated at 90° C. for 36 hours. The reaction mixture was then evaporated and purified by triggered LC/MS to give 4-(cyclopropylmethyl-amino)-benzenesulfonic acid 2-[3-(2-morpholin-4-yl-ethyl)-ureido]-1H-benzoimidazol-5-yl ester as an off-white solid (27 mg). Mass spectrum: 515 [M+H]+; retention time=5.97 minutes.
