Participants

Reaction Steps

To a solution of Benzothiazole-4-carbaldehyde (1.96 g, 12 mmol) in MeOH (50 mL) was added aminoacetaldehyde diethyl acetal (1.74 mL, 12 mmol) and acetic acid (1.03 mL, 18 mmol). The reaction mixture was stirred at room temperature for 1 h. The reaction mixture was added to a stirred solution of sodium cyanoborohydride (16 mg, 13 mmol). The reaction mixture was stirred at room temperature for 12 h. The reaction mixture was concentrated under reduced pressure. Then H2O and ethyl acetate were added to the reaction mixture. The organic layer was washed with H2O and brine, dried over Na2SO4, and concentrated under reduced pressure. The crude compound was used next step without further purification.
