o-(Bromoacetyl)phenyl acetate (5.0 g, 19.5 mmol) was treated with crude thioformamide (filtrate concentrated in vacuo from reaction of P2S5 (1.1 eq.) and (25 mmol) formamide in THF (30-40° C., 5 hours)) in refluxing acetone (60 mL). After 16 hours the reaction mixture was cooled to about 10° C. and the precipitated HBr salt of 2-(thiazol-4-yl)phenol was recovered. 31%, 1.50 g, LSIMS m/z=178 (MH+).
