Procedure

Coupling of 6-(benzyloxy)-1-butyl-5-oxo-1,2,3,5-tetrahydroimidazo[1,2-a]pyrimidine-7-carboxylic acid (0.300 g, 0.87 mmol) and 4-fluorobenzylamine (0.120 g, 0.96 mmol) as described for the synthesis of intermediate 3 gave 0.349 g (88% yield) of the title amide as white crystals; mp 107-109° C. (ethyl acetate-hexane). 1HNMR 400 MHz (CDCl3) δ (ppm): 0.96 (3H, t, J=7.3 Hz, CH3), 1.33-1.43 (2H, m, CH2), 1.56-1.63 (2H, m, CH2), 3.41 (2H, t, J=7.4 Hz, CH2), 3.70 (2H, t, J=8.9 Hz, CH2), 4.13 (2H, t, J=8.9 Hz, CH2), 4.50 (2H, d, J=5.8 Hz, NCH2), 5.10 (2H, s, OCH2), 7.0 (2H, m, aromatics), 7.25 (2H, m, aromatics), 7.33-7.37 (3H, m, aromatics), 7.46-7.48 (2H, m, aromatics), 7.68 (1H, broad t, NH). MS (ESI+) m/e 451 [M+H+].
