PROCEDURE

实验过程

A mixture of (S)-2-(2-bromo-7-(4-chlorophenyl)-5-methylbenzo[d]thiazol-6-yl)-2-tert-butoxyethyl pivalate (0.190 g, 0.35 mmol), 2-chloropyridin-4-ylboronic acid (0.66 g, 0.42 mmol), Pd(PPh3)4 (0.020 g, 0.0175, aq. 2M potassium carbonate solution (0.7 mL, 1.4 mmol) in degassed dioxane (2.0 mL) was heated at 90° C. for 3 hr. LC/MS indicated a 1.5:1 ratio of (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. Reaction mixture was used in next step without further purification.
