Reaction Steps
6.65 g of NaBH3CN are solubilized in acetic acid (10.5 g; 175 mmoles). The solution is cooled at 0° C. and a solution in anhydrous THF (35 mL; 0.15 M) of t-butyl-2-pentylidenhydrazincarboxylate (7.00 g; 35 mmoles) prepared in example 11a is dropwise added. The reaction mixture is then let to warm to room temperature under stirring for 24 hours. The organic phase is washed with a 10% NaHCO3 solution and then extracted with chloroform. The organic phase is recovered and the solvent removed under vacuum. The obtained residue is purified by chromatography on silica gel using as eluent a chloroform/methanol 90:1 volume/volume mixture. 6.3 g of t-butyl-2-pentylhydrazincarboxylate are obtained (white solid; yield 90%).
