(R)-2-methyl-1-phenyl-2-(pyridin-2-yl)propan-1-amine is prepared starting from racemic 2-methyl-1-phenyl-2-(pyridin-2-yl)propan-1-amine using chiral SFC chromatography. This oil is dissolved in isopropyl acetate and a solution of 5-6 N HCl in isopropyl alcohol is added. The mixture is concentrated, and triturated in ether to yield 3 as a white solid. M.p.=188° C. 1HNMR (300 MHz, CD3OD): δ 1.59 (s, 3H), 1.76 (s, 3H), 5.09 (s, 1H), 7.25-7.28 (m, 2H), 7.38-7.40 (m, 3H), 8.00 (t, J=6.6 Hz, 1H), 8.11 (d, J=6.9 Hz, 1H), 8.56 (t, J=7.8 Hz, 1H), 8.77 (d, J=5.7 Hz, 1H). MS: m/z 227.
