Procedure

To the a solution of 3-Benzyl-3-aza-bicyclo[4.1.0]hept-1-ylmethyl)-phenyl-amine (175) (250 mg, 0.86 mmol) in CH2Cl2 (2 ml) at 0° C. was added i-Pr2NEt (0.30 ml, 1.72 mmol)) and propionyl chloride (0.11 ml, 1.29 mmol). The mixture was stirred for 2 hrs. The mixture was diluted with CH2Cl2 (5 ml), washed with sat. NaHCO3 (2×5 ml), brine (5 ml) and water (5 ml) and dried with Na2SO4. After filtration, the filtrate was concentrated under vacuum. The residue was purified by silica gel chromatography (0.5% to 2% MeOH in CH2Cl2) to give 176 as a colorless oil. 1H-NMR (300 MHz, CDCl3) δ7.41-7.20 (m, 10H), 4.20 (d, 1H), 3.42 (AB, 2H), 3.21 (d, 1H), 2.65 (q, 2H), 2.20-2.00 (m, 4H), 1.80-1.60 (m, 2H), 1.30 (m, 1H), 1.05 (t, 3H), 0.80-0.20 (m, 2H) ppm; LRMS (calculated for C23H28N2O) 348, found 348; IR (film) 3308, 3105, 3064, 2978, 2937, 2874, 2811, 1689 m 1666, 1598, 1540, 1499, 1445, 1314, 1246, 1196, 1074, 757 cm−1.
