반응 단계
to a solution of 25.8 g (0.3 mol) methacrylic acid and 1.8 g (0.011 mol) 2,4-dinitrotoluene in 25.2 g (0.3 mol) dihydropyran was added 0.05 ml (0.0015 mol) concentrated hydrochloric acid. The reaction mixture was allowed to stir at 50° C. for 25 hr. The hydrochloric acid was neutralized with solid sodium bicarbonate and the mixture was filtered. The filtrate was distilled to give 46.5 g (0.273 mol, 91% yield) tetrahydropyran-2-yl methacrylate, bp 50° C. at 0.15 torr.
