Stannous chloride dihydrate → HCID 86641449, compound

Participants

Reaction Steps

Tin(II) chloride dihydrate was added (6.5 g, 28.67 mmol) to a solution of 2,2,2-trifluoro-N-(3-(3-nitrophenyl)prop-2-ynyl)acetamide (1.95 g, 7.16 mmol) in ethanol and the reaction mixture was stirred under reflux overnight. The mixture was concentrated under reduced pressure to give dark brown viscous liquid which was partitioned between saturated aqueous NaHCO3 and EtOAc. Organic layer was dried over anhydrous sodium sulfate and concentrated under reduced pressure to give N(3-(3-aminophenyl)prop-2-ynyl)-2,2,2-trifluoroacetamide as brown oil. Yield (0.75 g, 43%); 1H NMR (400 MHz, DMSO-d6) δ 7.28 (s, 1H), 6.94 (t, J=7.8 Hz, 1H), 6.44-6.37 (m, 3H), 5.09 (bs, 2H), 3.99 (s, 2H).
