Reaction Steps

A solution of (7RS,9aRS)—S-(7-aminomethyl-octahydro-pyrido[1,2-a]pyrazin-2-yl)-2-furan-2-yl-[1,2,4]triazolo[1,5-a][1,3,5]triazin-7-ylamine (1 eq.; see Example 9 above) and 2-chloropyrimidine (2 eq.) in DMSO was treated with K2CO3 (2 eq.). The mixture was stirred at around 85° C. for 4 hours. The reaction mixture was then filtered, and the filtrate was concentrated and purified by preparative HPLC using aqueous CH3CN (buffered with 0.1% TFA) to afford (7RS,9aRS)-2-furan-2-yl-5-[7-(pyrimidin-2-ylaminomethyl)-octahydro-pyrido[1,2-a]pyrazin-2-yl]-[1,2,4]triazolo[1,5-a][1,3,5]triazin-7-ylamine as a white powder: 1H NMR (400 MHz, DMSO-d6) δ 1.60-1.86 (m, 4H), 2.21-2.30 (bs, 1H), 3.05-3.32 (m, 4H), 3.33-3.52 (m, 4H), 3.56-3.72 (m, 1H), 4.62-4.83 (m, 2H), 6.63 (t, J=4.8 Hz, 1H), 6.69 (dd, J=1.8, 3.4 Hz, 1H), 7.08 (d, J=3.4 Hz, 1H), 7.41 (t, J=5.6 Hz, 1H), 7.89 (d, J=1.8 Hz, 1H), 8.32 (d, J=4.8 Hz, 2H), 8.40-8.65 (m, 2H). MS m/z: 448 [M+H]+.
