Procedure

A mixture of crude (+/−)-1-cyclohexyl-1-{2-[4-(trifluoromethyl)phenyl]pyrimidin-5-yl}methanamine (405 mg, 1.21 mmol), methyl 6-fluoronicotinate (225 mg, 1.45 mmol), and potassium carbonate (501 mg, 3.62 mmol) in N,N-dimethylformamide (4.2 ml) was heated to 120° C. for 12 hours. The reaction mixture was diluted with water to precipitate a crude solid that was collected by filtration. The crude material was purified via ISCO MPLC (SiO2, 0-50% ethyl acetate in heptane) to yield the product (0.486 g, 86%) as a solid. 1H NMR (400 MHz, CDCl3, δ): 8.78 (s, 2H), 8.70 (d, J=1.6 Hz, 1H), 8.55 (d, J=8.2 Hz, 2H), 7.94 (dd, J=8.8, 2.0 Hz, 1H), 7.74 (d, J=8.2 Hz, 2H), 6.31 (d, J=8.8 Hz, 1H), 5.38 (d, J=7.0 Hz, 1H), 4.76 (t, J=6.9 Hz, 1H), 3.84 (s, 3H), 1.97 (d, J=12.5 Hz, 1H), 1.59-1.88 (m, 5H), 1.04-1.34 (m, 5H). MS (M+1): 471.2.
