Procedure

To a mixture of {4-[4-(5-amino-pyridin-2-yl)-phenyl]-cyclohexyl}-acetic acid methyl ester (100 mg, 0.3 mmol) in methylene chloride (10 ml) was added triethylamine (43 ul, 0.3 mmol) and trimethylacetyl chloride (40 ul, 0.3 mmol). After 15 hours at room temperature, the reaction was diluted with hexanes to afford a precipitate which was collected by filtration: 1H NMR (400 MHz, DMSO-d6) δ ppm 1.15 (dd, J=12.69, 1.71 Hz, 2 H) 1.26 (s, 10 H) 1.42-1.56 (m, 1 H)1.50 (d, J=9.85 Hz, 1 H) 1.82 (d, J=11.37 Hz, 5 H) 2.26 (d, J=6.69 Hz, 2 H) 3.61 (s, 3 H) 7.32 (d, J=8.34 Hz, 2H) 7.87 (d, J=8.72 Hz, 1 H) 7.95 (d, J=8.34 Hz, 2 H) 8.15 (dd, J=8.72, 2.53 Hz, 1 H) 8.88 (d, J=2.53 Hz, 1 H)9.53 (s, 1 H); (M+H)+ 409.2.
