Participants

Reaction Steps

30% H2O2 (28.7 mL, 281.0 mmol) was slowly added to a 0° C. mixture of 3-(2-chlorooxazol-5-yl)benzonitrile (8.20 gm, 40.10 mmol) and K2CO3 (3.88 gm, 28.10 mmol) in DMSO (75 mL). The ice bath was removed and the reaction mixture was stirred at rt. After 24 h the reaction mixture was partitioned between EtOAc and water. The organic phase was isolated, washed with saturated aqueous NaCl (2×), dried over MgSO4, filtered and concentrated to give the product, 3-(2-chlorooxazol-5-yl)benzamide, (7.00 gm, 31.40 mmol, 78% yield) as a light yellow solid. Anal. Calcd. for C10H7ClN2O2 m/z 222.0, found: 223.0 (M+H)+. Crude product was used without purification.
