Reaction Conditions

Reaction Steps

To a solution of compound 1-I (85.2 mg, 0.37 mmol) in MeCN (1.0 mL) was added a solution of compound 1-C (120.8 mg, 0.74 mmol) in MeCN (1.0 mL) and the reaction mixture was heated under microwave irradiation at 140° C. for 10 minutes. The reaction mixture was purified by reverse-phase semi-prep HPLC (method 3) eluting with a 45% MeCN—H2O (0.1% TFA) to 65% MeCN—H2O (0.1% TFA) gradient to afford 46 mg of compound 1-J as a film. 1H-NMR (CDCl3, 400 MHz): δ 7.71-7.73 (t, 1H), 7.63-7.66 (t, 1H), 7.34-7.40 (m, 2H), 6.28 (s, 1H), 3.27-3.29 (m, 4H), 2.39 (s, 3H), 1.53-1.73 (m, 6H); MS (method 2): m/z 311.0 (M+1).
