p-Toluenesulfonic acid → HCID 67171703, compound

Participants

Reaction Steps

6-methoxy-3,4-dihydronaphthalen-2(1H)-one (460 mg, 2.61 mmol) was dissolved in N,N-dimethylformamide dimethyl acetal (8 mL, 26.1 mmol) at room temperature. Within 5 minutes the solution had turned dark green in color. Next, p-toluenesulfonic acid (10 mg, 0.053 mmol) was added and the reaction mixture was stirred at room temperature for 2 hours. The reaction mixture was concentrated under reduced pressure and dried under vacuum to afford the title compound as a dark red oil. LC/MS M+1=232.2. The material was used for subsequent reactions without further purification.
