2-Bromopropane → Methyl 2-(4-isopropoxyphenyl)acetate

関与物質

反応手順

Methyl 2-(4-hydroxyphenyl)acetate (10 g, 60.2 mmol), 2-bromopropane (6.49 mL, 69.2 mmol), and potassium carbonate (8.32 g, 60.2 mmol) were heated to 50° C. in DMF (100 mL) for overnight. The reaction was filtered and the organic layer was concentrated under vacuum. The crude material was purified by silica gel chromatography using a gradient of 0-20% EtOAc/hexanes. The product fractions were collected and the solvent removed under vacuum to give methyl 2-(4-isopropoxyphenyl)acetate (10 g, 80% yield). 1H NMR (400 MHz, CHLOROFORM-d) δ ppm 7.22-7.14 (m, 2H), 6.88-6.82 (m, 2H), 4.53 (spt, J=6.1 Hz, 1H), 3.70 (s, 3H), 3.57 (s, 2H), 1.34 (d, J=6.0 Hz, 6H).
