Reaktionsschritte
Triethylamine (7.28 ml) was added to a solution of α-chlorobenzaldehyde oxime (4.04 g) and 2-propyn-1-ol (1.66 ml) in tetrahydrofuran (130 ml) and stirred at room temperature for 4 days. Water was added to the reaction mixture and extracted with ethyl acetate. The ethyl acetate layer was washed with an aqueous saturated solution of sodium chloride, dried (MgSO4) and concentrated. The remaining crystals were recrystallized from ethyl acetate-hexane to obtain (3-phenyl-5-isoxazolyl)methanol (3.42 g, yield 75%) as colorless crystals. m.p. 48-49° C.
