YieldReaction ConditionsOperation in experiment
With potassium carbonate; In acetonitrile; at 105℃; for 20.0h; Alectinib (30 mg, 0.621 mmol, 1.0 eq.) was added to dry MeCN(3.0 mL) in a v-vial, and then anhydrous K2CO3 (62 mg, 0.4 mmol,7.0 eq.) was added. To this mixture, ethylene glycol ditosylate(32 mg, 0.09 mmol, 1.4 eq.) was added; the suspension becameclear after heating at 105 C for 10 min. The reaction mixture washeated at 105 C for 20 h. TLC (5% MeOH/CH2Cl2) showed a higher Rf(0.6) spot at about 65% intensity as compared with the startingmaterial (0.3 in 5% MeOH/CH2Cl2). The reaction mixture wasfiltered andwashed with 10% MeOH/CH2Cl2 (10 mL), and the filtratewas evaporated under vacuum. The crude product was purified byflash chromatography on silica gel and eluted with 2% MeOH/CH2Cl2 to obtain p-toluenesulfonylethyl alectinib (compound 7b) asa pale-yellow solid (24 mg, 57% yield). 7b: Rf 0.6 in 5% MeOH/CH2Cl2; 1H NMR (CDCl3, 600 MHz) d: 8.61 (d, J 8.1 Hz, 1H), 8.21 (s,1H), 7.52 (t, J 8.1 Hz, 3H), 7.45 (s, 1H), 7.16 (d, J 7.9 Hz, 3H), 4.80(t, J 6.4 Hz, 2H), 4.42 (t, J 6.3 Hz, 2H), 3.77 (t, J 3.9 Hz, 4H), 3.31(d, J 11.6 Hz, 2H), 2.75 (m, J 7.6 Hz, 4H), 2.63 (t, J 4.2 Hz, 4H),2.38 (s, 3H), 2.01 (d, J 11.8 Hz, 2H),1.85 (s, 6H),1.74 (dq, J 11.8 Hz,2H), 1.64 (s, 1H), 1.34 (t, J 7.5 Hz, 3H). 13C NMR decoupled (CDCl3,150 MHz) d: 180.55, 156.80, 156.26, 147.66, 145.78, 137.74, 136.25,131.29, 130.03, 128.34, 127.57, 126.71, 125.77, 123.50, 119.72, 115.94,113.74, 112.01, 106.39, 67.34, 65.55, 61.95, 52.16, 49.99, 44.19, 37.60,29.57, 28.96, 23.20, 21.69, 14.40.
