3-Amino-1-adamantanol → (2S,5R)-5-ethynyl-1-{N-((5R,7S)-3-hydroxy-1-adamantyl)glycyl}pyrrolidine-2-carbonitrile

Participants

Reaction Steps

To a stirred solution of Example 8D (0.06 g, 0.305 mmol ) in acetonitrile (3 mL ) at room temperature under nitrogen, was added 3-amino-1-adamantanol (0.1 g, 0.61 mmol ). The reaction mixture was stirred for two days and then concentrated under reduced pressure. The residue was flash chromatographed with 5-7% MeOH/CH2Cl2 to provide the desired compound as a pale yellow oil. MS (DCI) m/z 328 (M+H)+; 1H NMR (300 MHz, DMSO-d6) δ 1.5-2 (14H, m), 2.11-2.21 (2H, m), 2.45-2.48 (2H, m), 3.78 (1H, d), 3.8-4.5 (2H, m), 4.53-4.55 (1H, t), 5.01 (1H, m), 5.05 (1H, m).
