Sodium Hydroxide → HCID 9951149, compound

Participants

Reaction Steps

Sodium hydroxide solution (0.94 ml of 1M, 0.94 mM) was added to a solution of 2-methyl-4-isobutoxy-6-[N-(5-methoxycarbonylpyridin-2-yl)carbamoyl]benzofuran (Method 1; 120 mg, 0.314 mM) in a methanol/THF mixture (1 ml+4 ml), and the resulting solution stirred at ambient temperature. After 4 hrs the reaction mixture was diluted with water (5 ml) and concentrated to half volume in vacuo. The resulting mixture was acidified to pH6 with 1M HCl. The resulting solid precipitate was filtered, washed with water, and dried to give a pale cream solid. This was chromatographed (10 g Bondelut), eluting with DCM containing methanol (0-10% gradient) to give the title compound as a colourless solid. NMR: 1.03 (d, 6H), 2.09 (sept, 1H), 2.45 (s, 3H), 3.97 (d, 2H), 6.66 (s, 1H), 7.44 (s, 1H), 7.85 (s, 1H), 8.31 (t, 2H), 8.87 (s, 1H), 11.10 (bs, 1H); m/z 367 (M+H)+.
