実験手順

A solution of lapatinib ditosylate was converted to its free base form, lapatinib, by washing a solution with aqueous NaOH followed by concentration. Lapatinib: 1H NMR (300 MHz, d6-DMSO): δ 2.98 (t, J=6.75 Hz, 1H), 3.04 (s, 1H), 3.29 (t, J=6.6 Hz, 1H), 3.83 (s, 1H), 5.28 (s, 1H), 6.50 (d, J=3.0 Hz, 1H), 7.08 (d, J=3.3 Hz, 1H), 7.20 (m, 1H), 7.33 (m, 4H), 7.48 (m, 1H), 7.76 (m, 1H), 7.80 (d, J=9 Hz, 1H), 8.04 (d, J=2.75 Hz, 1H), 8.17 (dd, J=8.7 Hz, J=1.8 Hz, 1H), 8.56 (s, 1H), 8.75 (d, J=1.8 Hz, 1H).
