Trifluoroacetic acid → 2-Bromo-4,5,6,7-tetrahydrothiazolo[5,4-c]pyridine trifluoroacetate

Participants

Reaction Steps

2-Bromo-5-tert-butoxycarbonyl-4,5,6,7-tetrahydrothiazolo[5,4-c]pyridine (890 mg) was dissolved in dichloromethane (2 ml), and to the solution trifluoroacetic acid (15 ml) was added, and the mixture was stirred at room temperature for 1 minute. The reaction mixture was concentrated under reduced pressure, and diethyl ether was added to the residue. Precipitated solid materials were collected by filtration to obtain the title compound (867 mg) as a colorless solid.
