Versuchsvorschrift

A solution of 0.24 g (1.44 mmol) of trans-3-(4-Methylamino-cyclohexyl)-prop-2-yn-1-ol, 0.7 ml (5.74 mmol) of 2-chloro-5-ethylpyrimidine, 0.83 ml (4.88 mmol) N-ethyldiisopropylamine and a catalytic amount of NaI in 1.5 ml DMA was heated in the microwave oven for 3.75 h at 120° C. The reaction was cooled and partitioned between aqueous saturated NaHCO3/Et2O (3×). The organic phases were washed with aqueous 10% NaCl, dried (NaSO4) and evaporated. Flash chromatography on silica gel (hexane/EtOAc 9:1 to 1:1) gave 0.24 g (61%) of trans-3-{4-[(5-Ethyl-pyrimidin-2-yl)-methyl-amino]-cyclohexyl}-prop-2-yn-1-ol, MS: 274 (MH+).
