Procedure
As in part (d) of Example, 1, 6-amino 1,3-bis(cyclohexylmethyl)-5-nitrosouracil (from step (c) example 1, 2.79 g, 8.00 mmol) was reduced to 1,3-bis(cyclohexylmethyl)-5,6-diaminouracil, and condensed with 3-formylcinnamic acid (T. Higa, A. J. Krubsack, J. Org. Chem. 1975, 40: 3037-3045, 1.424 g) to give (E)-3-[1,3-bis(cyclohexylmethyl)-1,2,3,6-tetrahydro-2,6-dioxo-9H-purin-8-yl]cinnamic acid as an off-white solid (1.947 g, 49%), m.p. >350° C.; 1H-NMR (DMSO-d6) consistent with structure.
