실험 절차

Prepared using General Procedure 1. To hydroxylamine hydrochloride (0.87 g, 12.5 mmol) and sodium carbonate (1.32 g, 12.5 mmol) in EtOH (20 mL) was added 1-hydroxy-2,3-dihydro-1H-indene-4-carbonitrile INT-46 (1.80 g, 11.3 mmol) in one portion and the solution was heated to reflux. After 16 h, the reaction was cooled and filtered to remove the solids. The EtOH was removed and the compound was purified by chromatography (MeOH/DCM) to give 1.74 g (90%) of N,1-dihydroxy-2,3-dihydro-1H-indene-4-carboximidamide INT-47 as a white foam. LCMS-ESI (m/z) calculated for C10H12N2O2: 192.1; found: 193.1 [M+H]+, tR=0.56 min. 1H NMR (400 MHz, MeOD) δ 10.30 (s, 1H), 9.97 (s, 1H), 7.72-7.58 (m, 1H), 7.46-7.37 (m, 2H), 5.22 (t, J=6.5, 1H), 3.17-3.03 (m, 1H), 2.99-2.83 (m, 1H), 2.49 (dddd, J=11.4, 8.0, 7.0, 4.4, 1H), 2.02-1.88 (m, 1H).
