The reaction of 5-(chlorosulfonyl)-2-propoxybenzoic acid (I) with 2-(1-methylpyrrolidin-2-yl)ethylamine (II) in acetone gives the sulfonamide (III), which is treated with 2,4,6-trichlorobenzozyl chloride (IV) and TEA to afford the active mixed anhydride (V). The condensation of (V) with 4-amino-1-methyl-3-propyl-1H-pyrazole-5-carboxamide (VI) in dichloromethane provides the corresponding carboxamide (VII). Finally, this compound is cyclized by means of tBu-OK in refluxing tert-butanol to furnish the target pyrrolo-pyrimidinone.
