Reaction Steps

A mixture of 6-chloro-pyrimidin-4-ylamine (0.65 g, 5 mmol), 4-amino-N,N-diethylaniline (0.82 mL, 5 mmol), 2-propanol (5 mL) and HCl conc. (0.225 mL, ˜2.5 mmol) is shaken for 36 h at 90° C. After cooling to room temperature, the reaction mixture is distributed between half-saturated K2CO3-solution and ethyl acetate. The precipitate thus formed is filtered off, washed with H2O and ethyl acetate and dried in vacuo to afford the title compound. Greyish solid, HPLC: tR=2.37 min (gradient F), ESI-MS: 258.3 [MH]+.
