A solution of 4-chloro-6-(2-furyl)-5-methylpyrimidine-2-amine (80 mg, 0.38 mmol) in acetonitrile (4 mL) was treated with polymer supported cyamide (0.636 mg, 1.91 mmol), stirred at 140° C. in the microwave for 30 min, filtered to remove the resin and the filter cake washed with acetonitrile. The filtrate was concentrated in vacuo to give the title compound (50 mg, 65%) as off-white solid; NMR δH (400 MHz, DMSO) 2.48 (3H, s), 6.75 (1H, dd, J 1.7, 3.5 Hz), 7.04 (2H br s), 7.28 (1H, dd, J 0.7, 3.5 Hz) and 8.00 (1H, dd, J 0.7, 1.7 Hz); M/Z 201 (M=H)+; HPLC 1.1 min. (50/80).
