Reaction Conditions

Reaction Steps

Compound 10a (500 mg, 2.2 mmol) and N-ethylaniline (1 g, 5.5 mmol) were reacted in acetonitrile for 30 mins before diisopropylethylamine (284 mg, 2.2 mmol) was added dropwise. The reaction mixture was then heated and stirred at 70° C. for 12 hours. After cooling to room temperature, the solvent was evaporated and the residue was purified by silica gel column chromatography to provide the compound 10 (170 mg, 0.66 mmol, 24% yield) as a pale yellow solid. MS (ESI, positive) m/z calcd. for C17H21NO2 [M+H]+: 272.16, found: 272.00. 1H NMR (400 MHz, Chloroform-d) δ 7.25 (d, J=7.8 Hz, 2H), 6.88-6.66 (m, 7H), 3.99 (t, J=5.8 Hz, 2H), 3.53 (t, J=7.1 Hz, 2H), 3.41 (q, J=7.2 Hz, 2H), 2.08 (q, J=6.7 Hz, 2H), 1.19 (t, J=7.1 Hz, 3H).
