反応手順
To a solution of SnCl2 (1.5 g, 1.9 mmol) and 5.0 mL of HCl was added 7-ethyl-5-nitrobenzothiazole (0.12 g, 0.57 mmol) in a portion and resulting reaction mixture was stirred for 1 h at 25° C. The reaction mixture was basified with aqueous NaOH and extracted with EtOAc and CHCl3. Combined organic layers were dried over Na2SO4 and concentrated in vacuo, yielding an oil (0.10 g, >95%) which was identified as the desired amine (>95% pure) and subjected to a following reaction without further purification.
