実験手順

One-half of above reaction mixture containing S)-2-tert-butoxy-2-(7-(4-chlorophenyl)-2-(2-chloropyridin-4-yl)-5-methylbenzo[d]thiazol-6-yl)ethyl pivalate to (S)-2-(2-bromo-7-(4-chlorophenyl)-5-methylbenzo[d]thiazol-6-yl)-2-tert-butoxyethyl pivalate (1.5:1 ratio) was telescoped into the subsequent reaction. 1-Methyl-1H-indazol-5-ylboronic acid was added to the previous reaction mixture and reaction continued was heated at 120° C. for 30 minutes to give (S)-2-tert-butoxy-2-(7-(4-chlorophenyl)-5-methyl-2-(2-(1-methyl-1H-indazol-5-yl)pyridin-4-yl)benzo[d]thiazol-6-yl)ethyl pivalate and (S)-2-tert-butoxy-2-(7-(4-chlorophenyl)-5-methyl-2-(1-methyl-1H-indazol-5-yl)benzo[d]thiazol-6-yl)ethyl pivalate.
