Reaction Conditions

Reaction Steps

Isopropylamine (2 mL, 48.72 mmol) was added to a solution of Example 57k (0.3 g, 0.59 mmol) in DMF (5 mL) and stirred at 80° C. for 3 h. The reaction mixture was concentrated, treated with water, and extracted with chloroform. The organic layer was washed with water, brine and concentrated to obtain the title compound which was purified using flash chromatography (silica gel, 2% methanol/chloroform). Yield: 0.16 g, (55.17%); 1H NMR (CDCl3,): δ 1.10 (d, 6H, 2CH3), 2.7 (s, 3H, CH3), 2.8 (q, 1H, CH), 2.86 (t, 2H, CH2), 3.41 (s, 2H, CH2), 3.7 (t, 2H, CH2), 3.92 (s, 3H, OCH3), 4.71 (s, 2H, CH2), 7.38 (d, 1H, Ar), 7.46 (d, 1H, Ar), 8.1 (s, 1H, Ar), 8.46 (s, 1H, Ar); MS: m/e (ES+) 493 (M+1).
