実験手順

To a stirred suspension of (2S,4R)-2-(4-cyclobutyl-[1,4]diazepane-1-carbonyl)-4-hydroxy-pyrrolidine-1-carboxylic acid tert-butyl ester (116 mg, 0.32 mmol) in toluene (0.65 ml) was added iodobenzene (129 mg, 0.63 mmol), copper (I) iodide (6 mg, 0.032 mmol), 3,4,7,8-tetramethyl-1,10-phenanthroline (15 mg, 0.063 mmol), and Cs2CO3 (206 mg, 0.63 mmol). The resulting suspension was heated at 100° C. in a capped scintillation vial with stirring for 2 days. The reaction mixture was filtered through diatomaceous earth, washing with CH2Cl2. The filtrate was dried and concentrated. Purification of the residue by FCC provided the desired product (97.7 mg, 70%). MS (ESI): mass calcd. for C25H37N3O4, 443.3; m/z found, 444.3 [M+H]+. 1H NMR (CDCl3): 7.30-7.25 (m, 2H), 6.96 (dd, J=14.5, 7.2 Hz, 1H), 6.85 (dd, J=7.7, 5.5 Hz, 1H), 5.04-4.91 (m, 1H), 4.88-4.71 (m, 1H), 3.89-3.43 (m, 6H), 2.92-2.79 (m, 1H), 2.70-2.20 (m, 6H), 2.07-1.74 (m, 7H), 1.71-1.52 (m, 2H), 1.43-1.41 (m, 9H).
