Reaktionsschritte

Part C: To a solution of the propargyl amine of part B (8 g, 22.63 mmol) and powdered K2CO3 (8.8 g, 56.6 mmol) in N,N-dimethylformamide (150 mL) was added 3,4-dimethoxyphenol (6.98 g, 45 mmol) at ambient temperature. The composition was heated to 90 degrees Celsius for 36 hours. The solution was concentrated under high vacuum and the residue was dissolved in ethyl acetate. The organic layer was washed with 1N NaOH, H2O and dried over MgSO4. Chromatography (on silica, ethyl acetate/hexane) provided phenoxy propargyl amine as light yellow gel (10 g, 90.9%).
