Participants

Reaction Steps

To a solution of (15p) (0.04 g, 0.123 mmol), PyBOP (0.135 g, 0.26 mmol) and DIEA (0.02 mL, 0.12 mmol) in CHCl3 (2 ml), 4-morpholin-4-yl-phenylamine (0.044 g, 0.247 mmol) were added. The mixture was stirred at room temperature for 16 hours, treated with AP-trisamine resin (0.25 g, 2.49 mmol/g), and finally the solvent was removed under reduced pressure after filtration from the resin. The resulting residual was purified by chromatography (Sep-Pak, 10 g) with ether to provide the desired product (16p) (0.024 g, 40%). 1H NMR (400 MHz, CDCl3) δ 7.90 (s, 1H), 7.50 (br s, 1H), 7.45 (dd, J=7.83, 1.57 Hz, 1H), 7.39 (d, J=9.39 Hz, 2H), 7.31-7.26 (m, 3H), 7.23 (dd, J=7.83, 1.57 Hz, 1H), 7.15-7.09 (m, 2H), 6.86-6.79 (m, 3H), 4.17 (d, J=7.04 Hz, 2H), 3.86-3.82 (m, 4H), 3.80 (s, 2H), 3.11-3.06 (m, 4H), 2.41-2.29 (m, 1H), 0.95 (s, CH3), 0.94 (s, CH3); MS (APCI+) m/z 485.2 (M+H) was detected.
