Participants

Reaction Conditions

Reaction Steps

Bromothiophene (0.31 g, 1.5 mmol) and aminoacetaldehyde diethyl acetal (0.3 g, 2.25 mmol) were combined with 1,4-dioxane (2 mL). CF3SO3H (0.45 g, 3.0 mmol) was added and the reaction mixture was stirred at 22° C. for 2 hr at which time the mixture was made basic with 10% KOH (aq.) and the aqueous layer was extracted with EtOAc (3×50 mL). The combined organic layers were washed with brine, dried over Na2SO4, filtered and the solvent removed in vacuo to afford the crude amine product.
