Procedure
A mixture of 1a (150 mg, 0.6 mmol) and 6-amino-1,3-dimethyl uracil (200 mg, 1.2 mmol) in propanol (5 ml) was refluxed overnight, concentrated, redissolved in DCM, washed with 5% aqueous HCl, water, dried over Na2SO4, and concentrated to give the crude product 7-amino-5-(2,4-dichlorophenyl)-1,3-dimethyl-2,4-dioxo-1,2,3,4-tetrahydropyrido[2,3-d]pyrimidine-6-carbonitrile (1b).
