Reaction Steps

B38 was prepared following the general procedure reported for B10 using A1 and 5,6,7,8-tetrahydro-1,6-naphthyridine hydrochloride. The title compound (B38) was purified by reverse phase RP-HPLC (column: C18), using H2O (0.1% TFA) and MeOH (0.1% TFA) as eluents; yield: 67.6 mg (17%), colorless amorphous solid. 1H NMR (400 MHz, d6-DMSO, 300K) δ 2.98 (bs, 2H), 4.12 (t, J=6.0 Hz, 2H), 4.26 (bs, 2H), 4.95 (s, 2H), 6.86 (bs, 2H), 7.02 (d, J=7.9 Hz, 1H), 7.25 (dd, J=7.8 Hz, J=4.7 Hz, 1H), 7.31 (t, J=7.9 Hz, 1H), 7.47-7.80 (bm, 2H), 7.83-8.10 (bm, 1H), 8.39 (dd, J=4.8 Hz, J=1.6 Hz, 1H), 8.30 (s, 1H), 9.77 (s, 1H). MS (ES) C18H19N7O2S requires: 397. found: 398 (M+H)+.
