Reaction Steps

To a stirred solution of cis-2-amino-cyclopentanecarboxylic acid amide (1 g, 0.008 mol) in methanol (20 mL, 0.5 mol) and water (10 mL, 0.6 mol) at 0° C. in an ice bath was added 2,4,5-trichloropyrimidine (1.7 g, 0.0094 mol) followed by sodium bicarbonate (1 g, 0.02 mol). The reaction mixture was warmed to room and stirred at room temperature for 24 h. The reaction mixture was diluted with water (25 mL) and washed with ethyl acetate (3×50 mL). The organic layers were dried over magnesium sulfate, filtered and concentrated in vacuo to give cis-2-(2,5-dichloro-pyrimidin-4-ylamino)-cyclopentanecarboxylic acid amide as a white solid (1.8 g, 80% yield). No further purification was needed. 1HNMR (400 MHz, CDCl3) δ 7.99 (s, 1H), 6.73 (d, 1H, J=6.8 Hz), 5.56 (broad s, 1H), 5.44 (broad s, 1H), 4.66 (p, 1H, J=7.5 Hz), 2.97 (q, 1H, J=7.5 Hz), 2.05-2.15 (m, 3H), 1.83-1.98 (m, 2H), 1.70 (m, 1H).
