Combine 4-(1,2,3,4-Tetrahydro-isoquinolin-6-yloxy)-benzamide (80.0 mg, 0.30 mmol), DMF (4 mL), Et3N (0.2 mL, 1.32 mmol), and Pentylbromide (0.1 mL, 0.66 mmol) in a 7 mL vial. Place vial on shaker at 70° C. for 72 hours and then added Ethyl acetate to reaction vial, wash with water and several times with 10% LiCl(aq), dry over Na2SO4. Concentrate the organic mixture and flash chromatograph using 2% 1N NH3 MeOH, 20% THF, 78% CH2Cl2 to afford 78.0 mg (77% yield) of the title compound: 1H NMR (500 MHz, CDCl3); 0.9-1.0 (3H, m), 1.3-1.4 (4H, m), 1.5-1.7 (2H, m), 2.4-2.6 (2H, m), 2.7-2.8 (2H, m), 2.8-3.0 (2H, m), 3.5-3.6 (2H, m), 6.8-6.8 (2H, m), 6.9-7.1 (3H, m), 7.7-7.9 (2H, m); MS m/z 339 (M+1).
