Participants

Reaction Steps

A stirred solution of 6-chloro-N-methyl-5-nitropyrimidin-4-amine (1.0 g, 5.3 mmol) in methanol (20 mL) was added triethylamine (2.0 mL, 14.3 mmol) and spiro[indoline-3,4′-piperidin]-2-one (1072.5 mg, 5.3 mmol). The mixture was stirred at ambient temperature for 2 h and then 10 wt % Pd on C (wet) was added. The resulting mixture was stirred under hydrogen for 18 hours, diluted with methanol, and was filtered through Celite. The filtrate was concentrated, and the resulting solid was triturated with a solution of 50% aqueous methanol. The methanol was removed in vacuo and the mixture was filtered and dried under reduced pressure. The resulting compound was submitted to next step without further purification. 1H NMR (400 MHz, DMSO-d6) δ 10.39 (s, 1H), 7.86 (s, 1H), 7.45 (d, 1H), 7.20 (td, 1H), 6.98 (t, 1H), 6.87 (d, 1H), 6.30 (q, 1H), 4.15 (s, 2H), 3.45 (dd, 2H), 3.26-3.18 (m, 2H), 2.86 (d, 3H), 1.97-1.88 (m, 2H), 1.82 (dd, 2H). MS (EI) for C14H20N6O: 325.6 (MH+).
