Participants

Reaction Steps

5-tert-Butyl-2,3-dihydro-1H-inden-1-ylamine (150 mg, 1.13 mmol) in diethyl ether (10 mL) was treated with 5-isocyanatoisoquinoline in diethyl ether. The mixture was stirred for 2 hours, filtered, and the filter cake was washed with diethyl ether to provide the title compound. NMR (DMSO-d6) 1.29 (s, 9H), 1.78-1.90 (m, 1H), 2.43-2.54 (m, 1H, buried under DMSO), 2.76-3.05 (m, 2H), 5.19 (m, 1H), 7.27 (m, 2H), 7.31 (m, 1H), 7.43 (d, 1H), 7.89 (t, 1H), 8.05 (d, 1H), 8.63 (d, 1H), 8.69 (d, 1H), 9.33 (s, 1H), 9.73 (s, 1H); MS (ESI+) 360 (M+H)+; Elemental: Calculated for C23H25N3O.HCl.0.5H2O: C68.22, H6.72, N10.38; Found: C68.31, H6.81, N10.16.
