Thiobenzamide → methyl 2-(5-methyl-2-phenyl-1,3-thiazol-4-yl)acetate

Participants

Reaction Steps

A solution of 13.13 g (95.7 mmol) of thiobenzamide and 5.0 g (23.9 mmol) of methyl 4-bromo-3-oxo-pentanoate in 25 mL of dry toluene was heated at 90° C. for 5 h. The solution was poured into EtOAc/water and the aqueous phase extracted with EtOAc. The organics were washed with brine, dried (MgSO4), filtered, and concentrated. The crude oil was purified by silica gel chromatography eluting with hexanes/EtOAc (3/1 to 2/1) to afford 4.14 g (70%) yield) of the title compound as a pale orange-colored oil: 1H NMR (CDCl3, 400 MHz) δ7.97 (m, 2H), 7.11 (m, 2H), 3.73 (s, 3H), 3.56 (s, 2H), 2.36 (s, 3H).
