Reaction Steps

2-methoxyethanamine (Aldrich, 0.350 g, 4.66 mmol) was added to a solution of 2,4-dichloro-6-methyl-1,3,5-triazine (0.80 g, 4.88 mmol) in dioxane (10 mL). Heat was generated. Hünig's base (1.0 mL, 5.73 mmol) was added and the mixture was stirred for 5 min. The mixture was partitioned between DCM (15 mL) and water. The organic phase was dried over Na2SO4 and concentrated. The resulting yellow oil was purified by chromatography on silica using EtOAc in hexane (20-80%) to give the desired product as a yellow solid (300 mg). LCMS (ES, pos.): calcd for C7H11ClN4O: 202.1. found: 203.0 (M+H)+. 1H NMR (400 MHz, CDCl3) δ 5.93 (br. s., 1H); 3.60-3.70 (m, 2H); 3.49-3.58 (m, 2H); 3.38 (s, 3H); 2.42 (d, 3H).
