Reaction Steps

The title compound is prepared as described in Example 144A but using 4-(4-ethylpiperazin-1-yl)-aniline (1 g, 4.88 mmol) and (6-chloro-pyrimidin-4-yl)-methyl-amine (Example 1) (771 1.81 g, 12.68 mmol, 1.3 eq.). Purification of the residue by silica gel column chromatography (DCM/MeOH, 93:7) followed by trituration in diethyl ether affords the title compound as a white solid: ESI-MS: 313.2 [MH]+; tR=1.10 min (gradient J); TLC: Rf=0.21 (DCM/MeOH, 93:7).
