실험 절차

To a colorless solution of 6-cyclopropylmethoxy-5-pyrrolidin-1-yl-pyridine-2-carboxylic acid ((S)-1-hydroxymethyl-3-methyl-butyl)-amide (Example 14b; 231 mg, 639 μmol) in DMF (25.6 mL) and CCl4 (6.4 mL) was added sodium azide (49.9 mg, 767 μmol) and triphenylphosphine (352 mg, 1.34 mmol). The resulting reaction mixture was stirred at 90° C. for 4 hours. After cooling to room temperature the solvent was removed in vacuo. The residue was partitioned between water and ethyl acetate; the organic phases were washed with brine, combined, dried with Na2SO4, filtered and concentrated in vacuo. The residue, a brown waxy solid, was purified by flash chromatography (silica gel, 50 g, 0% to 60% ethyl acetate in heptane) to give the title compound (110 mg, 45%) as white solid; MS (ESI) 387.3 (M+H)+.
