실험 절차

To a mixture of the (S)-methyl 3-((6-carbamoyl-2-chloropyrimidin-4-yl)amino)-2-hydroxypropanoate (0.408 g, 1.49 mmol) in dioxane (10 mL) was added 2-(4-(4-fluorophenoxy)phenyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane (0.517 g, 1.65 mmol), 2M aqueous Na2CO3 (1.50 mL, 3.00 mmol) and PdCl2(dppf) (0.066 g, 0.081 mmol). The reaction vessel was flushed with argon, sealed and heated at 100° C. overnight. After cooling, the reaction mixture was diluted with acetone and decanted. Water was added to the insoluble residue to make a suspension. The solid was filtered, washed successively with water, acetone, 1N aqueous HCl then MeOH. The solid was dried under vacuum at 40° C. to give the product (S)-3-((6-carbamoyl-2-(4-(4-fluorophenoxy)phenyl)pyrimidin-4-yl)amino)-2-hydroxypropanoic acid as a light tan powder (0.053 g, 0.13 mmol, 9% yield). 1H NMR (400 MHz, DMSO-d6): 12.61 (1H, s), 8.53 (2H, d, J=8.3 Hz), 8.27 (1H, s), 7.99-7.93 (1H, s), 7.73 (1H, s), 7.31-7.24 (2H, m), 7.19-7.13 (2H, m), 7.08-7.01 (3H, m), 5.60 (1H, s), 4.26 (1H, s), 3.90-3.80 (1H, s), 3.64-3.54 (1H, m). LC/MS: m/z=413.1 [M+H]+.
