A mixture of 4,4′-(6-chloro-1,3,5-triazine-2,4-diyl)dimorpholine (285 mg, 1.0 mmol), 2-(4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl)acetic acid. (315 mg, 1.2 mmol) and tetrakis (triphenylphosphine) palladium (0) (58 mg, 0.05 mmol) in 2M sodium carbonate aqueous solution (3 mL, 8 mmol) and 20 mL of DME was stirred at 80° C. for 2 hr. Then the reaction mixture was diluted with 50 mL of ethyl acetate and extracted with 1N NaOH (50 mL, three times)). The combined aqueous layers were neutralized to pH=6. Then the aqueous solution was extracted with ethyl acetate (50 mL, three times). The combined organic layers were washed with saturated sodium carbonate and brine. Then the organic layer was dried over anhydrous sodium sulfate and concentrated to give 2-(4-(4,6-dimorpholino-1,3,5-triazin-2-yl)phenyl)acetic acid (68 mg, 18% yield). HPLC: Rt=2.04 min; MS 386 [M+H].
