Versuchsvorschrift
A solution of 6-bromo-2-phenyl-1′-propyl-2′-(propylthio)spiro[chroman-4,4′-imidazol]-5′(1′H)-one (280 mg, 0.6 mmol) and NH4I (172 mg, 1.2 mmol) in NH3/EtOH (4 mL, 1.5 N) was heated at 110° C. in a tube in a microwave reactor for 2-2.5 h. After cooling, the mixture was concentrated in vacuo to give a residue, which was purified by preparative TLC to afford 2′-amino-6-bromo-2-phenyl-1′-propylspiro[chroman-4,4′-imidazol]-5′(1′H)-one (45 mg, 18%). 1H-NMR (MeOD): 0.93 (m, 3H), 1.66 (m, 2H), 2.04 (m, 1H), 2.25 (m, 1H), 3.56 (m, 2H), 5.83 (m, 1H), 6.87 (m, 1H), 7.06 (m, 1H), 7.31 (m, 2H), 7.40 (m, 4H).
