Versuchsvorschrift

To a solution of (S)-2-tert-butoxy-2-(7-(4-chlorophenyl)-5-methyl-2-(3-(piperazin-1-yl)phenyl)benzo[d]thiazol-6-yl)acetic acid (30 mg, 0.055 mmol) in MeOH (1 mL) was added acetone (0.20 mL), acetic acid (0.08 mL), and sodium triacetoxyborohydride (58 mg, 0.27 mmol). Stirred at rt for 18 h then 60° C. for 3 h (reaction not to completion). H2O added (1 mL) and purified using reverse phase HPLC, eluting by 2-100% acetonitrile in H2O with 0.1% TFA to give the product. 1H NMR (400 MHz, CD3OD) δ 7.83 (s, 1H), 7.68 (m, 2H), 7.58 (m, 3H), 7.43 (t, J=8 Hz, 1H), 7.21 (d, J=8 Hz, 1H), 5.25 (s, 1H), 4.02 (m, 2H), 3.60 (m, 4H), 3.12 (m, 3H), 2.61 (s, 3H), 1.43 (d, J=7 Hz, 6H), 0.97 (s, 9H). LCMS-ESI+: calc'd for C33H39ClN3O3S: 592.2 (M+H+); Found: 592.3 (M+H+).
