実験手順
To a 0° C. suspension of 4-(isopropylamino)-2-(methylthio)pyrimidine-5-carboxylic acid chloride (as prepared in the above example, Preparation 16) in 30 mL of tetrahydrofuran is added 6.0 mL (46.3 mmol) of 4-methoxybenzylamine and 30 mL of tetrahydrofuran. The reaction suspension is allowed to warm briefly to room temperature, then stored at 0° C. overnight. The reaction mixture is diluted with dichloromethane, washed with 1N HCl and water. The combined aqueous phase is washed with dichloromethane. The combined organic phase is washed with a saturated solution of sodium bicarbonate and brine, dried over magnesium sulfate, filtered, and concentrated. The residue is crystallized from ethyl acetate/hexane to give 3.27 g (61%) of the title compound: mp 176-177° C.
