実験手順

Dry hydrogen chloride gas was bubbled through an ice cooled solution of N-(3-cyanophenyl)-N'-(1-benzylpiperidin-4-yl)cycloheptylurea (0.03 g, 0.077 mmol) in anhydrous ethanol (10 ml) under a nitrogen atmosphere for 15 min. The reaction was stoppered, allowed to warm to ambient temperature and stirred for 24 h. The reaction was concentrated to a solid and dissolved in anhydrous ethanol (5 ml) and ammonium carbonate (0.023 g, 0.23 mmol) was added. The reaction mixture was stirred at ambient temperature overnight then was concentrated in vacuo. N-(3-Amidinophenyl)-N'-(1-benzylpiperidin-4-yl)cycloheptylurea was purified by HPLC on a Vydec® C-18 column eluting with solvent mixture A (acetonitrile:water:TFA 80:20:0.3) and solvent mixture B (water:TFA 99.7:0.3) using a gradient starting with A:B at 3:97 and changing to A:B at 70:30 over 15 min. The major fraction eluting at 15 minutes was concentrated to give N-(3-amidinophenyl)-N'-(1-benzylpiperidin-4-yl)cycloheptylurea as an amorphous solid; LRMS (M+H)+ m/z 406, (M+2H)+2 m/z 203.8; 1H NMR (DMSO-d6): 9.52(broad s, 1H), 9.27(s, 2H), 9.02(s, 2H), 7.5(m, 9H), 4.3(m,m, 2H), 3.95(m, 1H), 3.67(m, 2H), 3.42(m, 2H), 3.2(m, 2H), 3.1(m, 2H), 2.05-1.6(m, 8H).
