Procedure

In two separate reaction vessels, (+) and (−)-ethyl N-({6-[(cyclohexyl{2-[4-(trifluoromethyl)phenyl]pyrimidin-5-yl}methyl)amino]pyridin-3-yl}carbonyl)-beta-alaninate (0.050 g, 0.090 mmol) were separately dissolved in methanol (0.2 ml) and tetrahydrofuran (0.10) and treated with aqueous lithium hydroxide (0.090 ml, 0.36 mmol, 2.0M aq.). The reactions were heated to 50° C. for 12 hours. The reactions were concentrated in vacuo, then diluted with water and acidified with aqueous 1.0M hydrochloric acid. The precipitated solids were collected for both acids and dried in vacuo to give the products as single enantiomers. 1H NMR (400 MHz, CD3OD, δ): 8.91 (s, 2H), 8.60 (d, J=8.2 Hz, 2H), 8.34 (s, 1H), 8.18 (d, J=8.0 Hz, 1H), 7.80 (d, J=8.2 Hz, 2H), 7.10 (d, J=9.4 Hz, 1H), 4.79 (d, J=8.0 Hz, 2H), 3.58 (t, J=6.7 Hz, 2H), 2.60 (t, J=6.7 Hz, 2H), 1.92-2.09 (m, 2H), 1.66-1.90 (m, 3H), 1.53 (d, J=12.3 Hz, 1H), 1.05-1.43 (m, 7H). MS (M+1): 528.4.
