실험 절차

Pyridine (3.64 mL, 45.0 mmol) was added to a solution of crude amine 80 (30.0 mmol) in CH2Cl2. The solution was cooled to 0° C. in an ice bath, then cyclopropyl carbonyl chloride (2.99 mL, 33.0 mmol) was added dropwise. The reaction was allowed to warm slowly to room temperature and stirred until the reaction was judged complete by TLC (3.25 h). CH2Cl2 and saturated NaHCO3 were added. The organic layer was removed and the aqueous layer extracted with CH2Cl2 (2×). The organic extracts were dried with sodium sulfate, filtered and concentrated in vacuo. The resulting oily residue was purified by alumina gel chromatography (96:2:2::Hexanes:CH2Cl2:2N NH3 in EtOH) to obtain 4-benzyl-1,4-ozazepan-2-ylmethyl)-N-phenylcyclopropanamide (85) as a pale yellow oil. 1H NMR (CD3OD) 7.46-7.24 (8H, m), 7.13 (2H, broad d, J=7.2 Hz), 3.90-3.42 (5H, m), 2.92-2.76 (2H, m), 2.62-2.51 (1H, m), 2.30 (1H, dd, 13.7, 8.5 Hz), 1.40-1.20 (2H, m), 0.96-0.82 (3H, m), 0.61 (2H, dd, J=7.9, 2.8 Hz) ppm. 13C NMR (CD3OD) 175.84, 144.04, 140.20, 130.82, 130.54, 129.55, 129.08, 128.43, 77.04, 68.00, 63.63, 59.72, 55.83, 52.94, 31.28, 13.76, 9.34, 9.07 ppm. LRMS: 364.57.
