실험 절차

The mixture of 2,6-dihydroxybenzoate (168 mg, 1.0 mmol) and 2 M methylamine in THF (3 mL, 6.0 mmol) in a sealed tube was heated to 100° C. overnight. The reaction mixture was then concentrated under reduced pressure and purified on silica gel eluting with hexane/ethyl acetate (1:1) to provide titled compound (67 mg). MS (ESI(+)) m/e 168 (M+H)+; 1H NMR (300 MHz, DMSO-d6) 12.57(bs, 2H), 8.82 (bs, 1H), 7.14 (t, 1H), 6.35 (d, 2H), 2.85(d, 3H).
