実験手順
To a suspension of the hydrazine of Step 1 (70 g) in toluene (1.2L) was added Et3N (107 mL) followed by 4-chlorobenzyl chloride (61 g). The resulting mixture was heated at reflux for 2 hours. The reaction mixture was cooled and Et2O (1.2L) was added. The triethylammonium hydrochloride salt was filtered off, and the filtrate concentrated under vacuum. The crude residue was purified by chromatography on a bed of silica gel eluting with hexane-EtOAc (6:4) to afford the pure title product as an oil.
