Reaction Steps

4-(3-Methyl-4,5-dihydrobenzo[g]indazol-1-yl)phenol (48 mg, 0.174 mmol) was dissolved in N,N-dimethylformamide (1 mL), and 1-(3-chloropropyl)pyrrolidine (31 mg, 0.21 mmol), sodium hydride (8 mg, 60% dispersion in mineral oil, 0.21 mmol) and sodium iodide (32 mg, 0.21 mmol) were added. The reaction was heated at 70° C. for 1.5 hours, then cooled to room temperature. Saturated sodium bicarbonate solution was added, and the mixture was extracted with ethyl acetate. The extracts were dried over MgSO4 and concentrated. SiO2 chromatography with ethyl acetate, then 2% triethylamine/10% methanol/ethyl acetate gave 27.4 mg of the desired product (40% yield). LC-MS (C25H29N3O calculated 387) m/z 388 (M+H); 1H NMR (300 MHz, CDCl3) δ 7.39-7.34 (m, 2H), 7.27 (d, J=7.5 Hz, 1H), 7.12 (t, J=7.5 Hz, 1H), 7.01-6.93 (m, 3H), 6.81 (d, J=7.8 Hz, 1H), 4.09 (t, J=6.3 Hz, 2H), 2.98 (t, J=6.9 Hz, 2H), 2.74-2.60 (m, 8H), 2.30 (s, 3H), 2.14-2.04 (m, 2H), 1.86-1.82 (m, 4H).
