Yamato, Masatoshi,Takeuchi, Yasuo,Hashigaki, Kuniko,Hirota, Takashi

, p. 733 - 736 (2007/10/02)

The effect of the solvent on the reaction of benzoxazoline-2-thiones with alkyl halides was studied.The reaction of 1 with alkyl halides and potassium carbonate in dimethylformamide (DMF) gave the corresponding 2-alkylthiobenzoxazoles (2), but the same reaction gave 2-methoxybenzoxazoles (4a) when methanol was used in place of DMF as the solvent.On the other hand, the reaction of 1, methyl iodide, alcohol, and sodium hydride in tetrahydrofuran (THF) gave 2-phenols (5).
