Procedure

(S)-tert-butyl 4-(3-(3-chloro-6-hydroxyphenyl)phenyl)-1,4-dimethyl-6-oxo-tetrahydropyrimidin-2(1H)-ylidenecarbamate (CF3; R1=R6=Me, R21=3-chloro-6-hydroxyphenyl) (23 mg, 0.05 mmol) was treated with 1 mL of 30% TFA/CH2Cl2 at RT for 30 min. The volatiles were removed in vacuo. The residue was redissolved in acetonitrile (5 mL) and evaporated again to afford 17 mg of the crude product as a yellow solid. The crude product was purified via reverse phase HPLC to provide 10 mg (60%) of (S)-6-(3-(3-chloro-6-hydroxy-phenyl)phenyl)-6-ethyl-2-imino-3-methyl-tetrahydropyrimidin-4(1H)-one (CF4; R1=R6=Me, R21=3-chloro-6-hydroxyphenyl) as a white solid. 1H NMR (CDCl3, 300 MHz): 11.4 (br s, 1H), 7.6-4.25 (m, 3H), 7.24-6.84 (m, 3H), 3.68 (br s, 1H), 5.18 (br s, 1H), 3.39 (d, J=16.1 Hz, 1H), 3.20 (s, 3H), 2.95 (d, J=15.8 Hz, 1H), 1.74 (s, 3H). MS (ESI): MH+=344.1. HPLC (A) Rt=5.07 min.
