実験手順
To a solution of 2-amino-6-ethylaminopyrimidine (98 g, 0.64 mol) in methanol (1.6 L) was added ICl (115.0 g, 0.71 mol) in a small portion at 15° C. Then the reaction mixture was stirred at room temperature for 3 h (monitored by LC/MS). After evaporation of solvent by rotary evaporator, the residue was triturated with acetone. 2-amino-6-ethylamino-4-iodopyrimidine hydrochloride (188.5 g, 93% isolated yield) was obtained by vacuum filtration and drying. 1H NMR (400 MHz, CD3OD) δ 3.58 (q, 2H), 2.14 (s, 3H), 1.11 (t, 3H); MS (EI) for C7H11N4ClI: 279.1 (MH+).
