3-(Hydroxymethyl)naphthalen-2-ol C화학적 특성, 용도, 생산
Synthesis
3-(hydroxymethyl)naphthalen-2-ol is prepared by reacting;Methyl 3-hydroxy-2-naphthoate with;sodium borohydride in;methanol.Methyl 3-hydroxy-2-naphthoate (100 mg, 0.49 mmol) was dissolved in methanol (7.0 ml) with stirring in a round bottom flask. Sodium borohydride (185 mg, 4.90 mmol) was then added in carefully into the reaction mixture in two portions with an interval time of 3 hours between them and left to react overnight. The resultant mixture was quenched with addition of water followed by extraction with ethyl acetate (3×10 ml). The organic extracts were collected, dried with magnesium sulphate and concentrated in vacuo to give the colourless powder title compound as a colourless powder (82 mg, 96%): mp: 193 – 195 ℃ (Lit.: 186 – 188 ℃);vmax/cm-1 3379 br. m (O-H), 2844 w (aro.
