Reaction Steps

A suspension of 6-(5-methyl-2-furyl)-5-nitropyrimidine-2,4-diamine (6.6 g, 29.6 mmol) and 10% Pd/C (0.66 g) in MeOH (100 mL) was heated at 40° C. under an atmosphere of H2 for 3 h, cooled to room temperature, filtered through Celite, and concentrated in vacuo to give the title compound (5.8 g, 99%) as an off-whited solid; IR νmax (DR)/cm−1 3333, 2237, 1634, 1458, 1237, 1025, 963 and 828; NMR δH (400 MHz, DMSO) 6.77 (1H, dd, J 0.5, 3.2 Hz), 6.21-6.17 (3H, m), 5.14 (2H, s), 4.21 (2H, s), and 2.35 (3H, s).
