Procedure

To a solution of 5-chloro-N-(8-(hydroxymethyl)-9-methyl-6,7-dihydro-5H-benzo[7]annulen-2-yl)picolinamide from step 3B (52 mg, 0.15 mmol) in dichloromethane (1 mL) was added methanesulfonylchloride (0.015 mL, 0.20 mmol) and DIPEA (0.048 mL, 0.27 mmol). The mixture was stirred at rt for 20 h. The mixture was subjected to chromatography (hexanes-100% EtOAc) to give 5-chloro-N-(8-(chloromethyl)-9-methyl-6,7-dihydro-5H-benzo[7]annulen-2-yl)picolinamide (30 mg, 0.083 mmol, 55% yield). LCMS (M+H)+=361.2. 1H NMR (500 MHz, chloroform-d) δ 9.81 (br. s., 1H), 8.58 (dd, J=2.3, 0.6 Hz, 1H), 8.27 (dd, J=8.4, 0.6 Hz, 1H), 7.90 (dd, J=8.4, 2.3 Hz, 1H), 7.70 (d, J=2.3 Hz, 1H), 7.57 (dd, J=8.1, 2.3 Hz, 1H), 7.20 (d, J=8.1 Hz, 1H), 4.37 (s, 2H), 2.57 (t, J=7.0 Hz, 2H), 2.21 (s, 3H), 2.17 (quin, J=7.1 Hz, 2H), 2.05-1.98 (m, 2H)
