Reaction Steps

A solution of {2-[5-(2-Aminomethyl-4-fluorophenoxy)-indazol-1-yl]-ethyl}-dimethylamine (0.020 g, 0.061 mmol) in DMF (1 mL) was treated with (3-tert-butylisoxazol-5-yl)-carbamic acid 4-nitrophenyl ester (0.020 g, 0.067 mmol) (prepared according to Example 136, Step E). The mixture stirred at room temperature for 18 hours under a N2 atmosphere. The reaction mixture was chromatographed eluting with dichloromethane/ether (10:1) and then 5% MeOH in dichloromethane to afford 5.3 mg of pale yellow oil (18% yield). MS (APCI+) m/z 495 (M+1) detected; 1H NMR (400 mHz, DMSO-D6) δ 10.14 (s, 1H), 7.98 (s, 1H), 7.74 (d, 1H), 7.22 (d, 1H), 7.16 (m, 2H), 7.08 (m, 1H), 6.88 (m, 2H), 5.93 (s, 1H), 4.48 (t, 2H), 4.35 (d, 2H), 2.70 (t, 2H), 2.17 (s, 6H), 1.23 (s, 9H).
