66% | With tris-(dibenzylideneacetone)dipalladium(0); potassium carbonate; XPhos; In tert-butyl alcohol; at 100℃; for 21.0h; | (R)-methyl l-(8-cyclopentyl-7-ethyl-5-methyl-6-oxo-5,6,7,8-tetrahydropteridin-2- yl)indoline-5-carboxylate (i?)-2-chloro-8-cyclopentyl-7-ethyl-5-methyl-7,8-dihydropteridin-6(5H)-one (44.2 mg, 0.150 mmol, 1 eq), methyl indoline-5-carboxylate (31.9 mg, 0.180 mmol, 1.2 eq), Pd2dba3 (6.9 mg, 0.0075 mmol, 5 mol%), XPhos (10.7 mg, 0.0225 mmol, 15 mol%) and K2C03 (82.9 mg, 0.60 mmol, 4 eq) were dissolved in tBuOH (1.5 mL, 0.1 M) and heated to 100 C for 21 hours. The mixture was filtered through celite, washed with DCM and condensed. Purification by column chromatography (ISCO, 4 g silica column, 0-100% EtOAc/hexanes, 18 minute gradient) gave the desired product as a yellow oil (43.4 mg, 0.0997 mmol, 66%). 1H NMR (400 MHz, Chloroform-;/) delta 8.30 (d, J= 8.6 Hz, 1H), 7.89 (dd, J= 8.6, 1.8 Hz, 1H), 7.82 (d, J= 1.3 Hz, 1H), 7.76 (s, 1H), 4.47 (p, J= 8.5 Hz, 1H), 4.32 - 4.19 (m, 3H), 3.88 (s, 3H), 3.33 (s, 3H), 3.18 (t, J= 8.8 Hz, 2H), 2.21 - 2.11 (m, 1H), 2.04 - 1.98 (m, 1H), 1.86 (ddt, J= 16.3, 8.7, 4.4 Hz, 4H), 1.76 - 1.62 (m, 4H), 0.87 (t, J= 7.5 Hz, 3H). 13C NMR (100 MHz, cdcl3) delta 167.22, 163.83, 154.78, 152.04, 148.37, 137.77, 132.00, 130.05, 125.80, 121.94, 115.94, 113.23, 60.15, 58.76, 51.72, 49.52, 29.62, 29.18, 28.13, 27.07, 26.65, 23.36, 23.02, 9.17.
