Hydrochloric Acid → HCID 59712044, compound

Participants

Reaction Steps

A mixture of 250 mg (0.52 mmol) 2-[(2,4-dichloro-benzoyl)-(4-trifluoromethoxy-phenyl)-amino]-thiazole-4-carboxylic acid, 57 μL (0.68 mmol) pyrrolidine and 110 mg (0.68 mmol) 1,1′-carbonyldiimidazole in 10 mL dichloromethane was stirred for 16 h at room temperature. The mixture was poured onto 0.5 N hydrochloric acid and extracted with dichloromethane. Organic phases were pooled, washed with water and brine and dried with MgSO4. Volatiles were removed in vacuo and the residue was purified by silica gel chromatography (n-heptane/ethyl acetate 1:1) to yield 182 mg (65%) of the title compound as colorless solid. MS (m/e): 530.0 (MH+)
