Reaction Steps

A mixture of 0.42 g (2.0 mmol) of trans-4-methylaminomethyl-cyclohexanecarboxylic acid•HCl, 1.85 mL (1.1 mmol) of Huenig's base and 0.57 g (2.4 mmol) of 2,5-dibromo-pyrimidine [Brown and Arantz, J. Chem. Soc. C Issue 10, 1889-1891 (1971)] in 2 mL of DMA was placed in the microwave and heated to 120° C. for 1 h. The solvent was evaporated, partitioned between Et2O (×3)/aqueous 10% KH2PO4, dried over Na2SO4 and evaporated to yield 0.604 g (92%) of trans-4-{[(5-bromo-pyrimidin-2-yl)-methyl-amino]-methyl}-cyclohexanecarboxylic acid, MS: 326 (M−H−, 1Br), MP: 172-174° C.
