To a flask containing 2,4-dichloro-5-chloromethyl-6-methyl-pyrimidine (107 mg, 0.51 mmol) in absolute ETOH (10 mL) is added K2CO3 (70 mg, 1.0 eq., 0.51 mmol) and the reaction is cooled to 0° C. with an ice bath. (1S)-Methyl-(1,2,3,4-tetrahydro-naphthalen-1-yl)-amine (82 mg, 1.0 equiv, 0.51 mmol) in 1.0 mL of EtOH is added via syringe in one portion and allowed to warm to ambient temperature over 3 h. Water (50 mL) and EtOAc (50 mL) is added and the EtOAc layer is washed with water (100 mL) and brine (50 mL) and dried over Na2SO4. Concentration and vacuum drying affords the title compound as a yellow gum. [mass expected (336.26); mass found (336.30)]
