实验步骤: 200 mg (0.467 mmol) of (2R*,4S*)-2-benzyl-N-(4-quinolylmethyl)-N-trifluoroacetyl-4-piperidinamine are reacted in analogy to Example 25a with 138 mg (0.561 mmol) of 9-bromofluorene and 155 mg (1.12 mmol) of potassium carbonate in 2.5 ml of acetone. The title compound (131 mg, 47%) is obtained as oil. TLC:toluene/ethyl acetate (1:1) Rf =0.43; FD-MS:M+ =591.

实验步骤: 9-Bromo-9H-fluorene (1.00 g, 4.08 mmol) was dissolved in acetone (7 mL). To this was added a solution of NaN3 (1.33 g, 20.4 mmol) in H2O (3 mL). The resulting solution was stirred overnight. Acetone was removed by concentration under reduced pressure. The resulting aqueous mixture was extracted with CH2Cl2 (2×15 mL), and the organic layers were combined, dried over Na2SO4(s), filtered, and concentrated under reduced pressure. The resulting solid residue was purified by silica gel flash chromatography, eluting with hexanes, to give azide 2j as a white solid (0.74 g, 3.57 mmol, 87% yield).
