Cyclobutylamine (0.192 g, 2.7 mmol) was added to a solution of Example 133 (0.600 g, 1.3 mmol) in DMF (1 mL). The reaction mixture was stirred at 120° C. for 4 h, concentrated, treated with water and the solid that precipitated was filtered, washed with water and purified using flash chromatography (silica gel, 3-4% methanol/chloroform) to obtain the title compound. Yield: 0.450 g, (66.6%); 1H NMR (CDCl3-d6): δ 1.80 (m, 6H, 3CH2), 1.94 (t, 3H, CH3), 2.2 (t, 1H, CH), 2.9 (s, 3H, CH3), 3.3 (s, 2H, CH2), 3.9 (s, 3H, CH3), 4.7 (s, 2H, CH2), 7.5 (s, 1H, Ar), 7.8 (s, 1H, Ar). 8.4 (s, 1H, Ar), 9.5 (s, 1H, Ar); MS: m/e (ES+) 423 (M+1).
