反应条件: temp:140.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: 6-Chloro-5-cyclopropyl-2-pyridinecarboxylic acid (CAN 1211530-95-8; 180 mg, 901 μmol), (S)-4,4,4-trifluorobutane-1,3-diol (394 mg, 2.73 mmol) and potassium tert-butoxide (307 mg, 2.73 mmol) were combined with DMF (3 mL) to give a white suspension. The reaction mixture was heated to 140° C. and stirred for 48 h. After cooling the mixture was poured into cold 1 M HCl (15 mL) and extracted with ethyl acetate (2×75 mL). The phases were combined, dried with Na2SO4 and concentrated in vacuo. The residue was purified by preparative HPLC to give the title compound (23 mg, 8.3%) and its regioisomer; MS (EI) 304.2 (M+H)+. to give a white suspension After cooling the mixture extracted with ethyl acetate (2×75 mL) dried with Na2SO4 concentrated in vacuo The residue was purified by preparative HPLC
