(S)-2-tert-butoxy-2-(7-(4-chlorophenyl)-2-(1,3-dimethyl-1H-indazol-6-yl)-5-methylbenzo[d]thiazol-6-yl)acetic acid → (S)-2-(2-(2-benzyl-3-methyl-2H-indazol-5-yl)-7-(4-chlorophenyl)-5-methylbenzo[d]thiazol-6-yl)-2-tert-butoxyacetic acid

Participants

Reaction Steps

Prepared in a manner similar to (S)-2-tert-butoxy-2-(7-(4-chlorophenyl)-2-(1,3-dimethyl-1H-indazol-6-yl)-5-methylbenzo[d]thiazol-6-yl)acetic acid, but using (S)-ethyl 2-(2-(2-benzyl-3-methyl-2H-indazol-5-yl)-7-(4-chlorophenyl)-5-methylbenzo[d]thiazol-6-yl)-2-tert-butoxyacetate instead of (S)-ethyl 2-tert-butoxy-2-(7-(4-chlorophenyl)-2-(1,3-dimethyl-1H-indazol-6-yl)-5-methylbenzo[d]thiazol-6-yl)acetate. LCMS-ESI+: calc'd for C35H33ClN3O3S: 610.2 (M+H+); found: 610.3 (M+H+). 1H NMR (400 MHz, CD3OD) δ 8.36 (s, 1H), 7.99 (dd, J=9.1, 1.6 Hz, 1H), 7.80 (s, 1H), 7.69 (d, J=8.6 Hz, 1H), 7.65 (d, J=9.1 Hz, 1H), 7.59 (t, J=3.4 Hz, 3H), 7.38-7.26 (m, 3H), 7.17 (d, J=7.0 Hz, 2H), 5.65 (s, 2H), 5.26 (s, 1H), 2.64 (s, 3H), 2.61 (s, 3H), 0.98 (s, 9H).
