Participants

Reaction Steps

To a stirred solution of 1-(5-Bromo-pyridin-2-yl)-2,2,2-trifluoro-ethanone (1.0 g, 3.93 mol) and methylamine (20 ml, tetrahydrofuran solution) is added titanium ethoxide (0.987 g, 4.33 mmole) at 0° C. then stirred at room temperature for 2 hours. Reaction mixture is diluted with saturated sodium bicarbonate solution and extracted with ethyl acetate. Organic layer is dried over sodium sulphate, concentrated and purified by column chromatography eluting in 20% ethyl acetate in hexane to give the title compound (0.10 g). 1H-NMR (400 MHz, DMSO) δ: 3.25-3.26 (m, 3H), 7.85-7.90 (m, 2H), 8.49 (s, 1H). LC-MS (m/z): [M+H]=266.8.
