Versuchsvorschrift

(1S,3S)-3-Amino-indan-1-ol (110 mg, 0.74 mmol) was added to a suspension of NaH (60% in mineral oil, 87 mg, 2.17 mmol) in anhydrous DMF (5 mL) at RT and stirred for 20 min. Intermediate 5b (160 mg, 0.72 mmol) was then added in one portion and the mixture heated at 60° C. for 3 h. After cooling the mixture was diluted with water (20 mL) and extracted with EtOAc (3×50 mL). The combined organics were washed with brine (50 mL), dried (MgSO4) and evaporated in vacuo. The residue was purified by FCC, using 0-10% MeOH in DCM, to give the title compound as give a foam (132 mg, 52%). LCMS (Method 1): Rt 0.34 min, m/z 350 [MH+]. 1H NMR (300 MHz, CDCl3): 1.95-2.16 (6H, m), 2.24 (3H, s), 2.26-2.45 (2H, m), 2.77 (1H, ddd, J 14.1, 7.0, 2.0), 3.23-3.30 (1H, m), 4.02-4.09 (1H, m), 4.71 (1H, t, J 6.8), 5.68 (1H, dd, J 6.2, 1.9), 7.04 (1H, dd, J 9.9, 2.2), 7.29-7.50 (4H, m), 7.64 (1H, dd, J 9.9, 0.9), 8.35 (1H, d, J 2.2).
