Participants

Reaction Steps

To a solution of (2-aminoethyl){2-methyl-6-[(2,4,6-trimethylphenyl)amino]pyrimidin-4-yl}amine (0.36 g, 1.26 mmol), 4-ethoxy-3-methoxyphenethylamine (0.26 g, 1.26 mmol)) and N,N diisopropylethyl amine (0.24 ml, 1.38 mmol in CH2Cl2 (5 mL), add benzotriazol-1-yloxytris-(dimethylamino)phosphonium hexafluorophosphate (0.61 g, 1.38 mmol) and stir at ambient temperature for 14 h. Dilute the resulting mixture with CH2Cl2 (20 mL), and wash with water (20 mL) and saturated aq NaCl (20 mL). Dry the organic layer over Na2SO4, filter and concentrate in vacuo. Purify by preparative TLC (7% methanol-CH2Cl2) to obtain the title compound.
