Participants

Reaction Steps

Triethylamine (85 μL, 0.61 mmol) was added to a solution of 8-[(1S,4S)-1-(2,5-diazabicyclo[2.2.1]hept-2-yl)methyl]-2-(2-ethylbenzoimidazol-1-yl)-9-methyl-6-morpholin-4-yl-9H-purine (250 mg, 0.53 mmol) and 2-chloroacetamide (60 mg, 0.64 mmol) in DCM (10 mL) The mixture was stirred at ambient temperature for 24 h, then loaded onto an Isolute® SCX-2 cartridge (10 g). The cartridge was then washed with methanol and the desired product was subsequently eluted using 2 M NH3 in MeOH. The product was collected and concentrated in vacuo. The resultant residue was purified by flash chromatography (Si—PPC, DCM:MeOH, 100:0 to 99:1 to 98:2) to afford 597 as a cream solid (175 mg, 62%). LCMS (method I): RT=2.35 min, M+H+=531. 1H NMR (CDCl3, 400 MHz) δ 12.12 (bs, 1 H), 8.01 (m, 1 H), 7.77 (m, 1 H), 7.26 (m, 2 H), 5.62 (bs, 1 H), 4.34 (m, 4 H), 3.92-3.83 (m, 9 H), 3.54 (m, 2 H), 3.37 (q, J=7.4 Hz, 2 H), 3.09 (m, 4 H), 2.93 (m, 2 H), 2.00 (m, 2 H) and 1.42 (t, J=7.4 Hz, 3 H)
