Procedure

4-Azidobenzoyl chloride (67 mg, 0.37 mmol) was added to a solution of [4-(2-aminoethylamino)-5-(4-fluorophenylcarbamoyl)pyrimidin-2-ylsulfanyl]acetic acid ethyl ester (145 mg, 0.37 mmol) in DMF (2.0 mL). DIPEA (100 μL, 0.55 mmol, 1.5 eq) was then added to the reaction mixture and the acylation was allowed to proceed overnight at ambient temperature. The reaction mixture was concentrated by rotary evaporation and purified using flash chromatography (4 g silica gel, 10 mL/min flow rate) to yield the titled product (31 mg, 16%) as a clear glass. 1H NMR: (d6-DMSO) δ 10.23 (s, 1H), 8.67 (m, 1H), 8.55 (s, 1H), 7.81 (d, 2H), 7.62 (m, 2H), 7.13 (m, 3H), 4.07 (q, 2H), 3.97 (s, 2H), 3.60 (m, 2H), 3.42 (m, 2H), 1.14 (t, 3H); HPLC: Rt=4.36 min; MS (ESI): m/z 537.31 (M−H)−; IR (KBr): 2126 cm−1.
