실험 절차

A solution of tert-butyl 3-(4-(6-chloropyrimidine-4-carboxamido)-3-methylphenylsulfonamido)propanoate (Intermediate 34, 140 mg; 0.31 mmol) and diisopropylamine (105.5 mL; 0.61 mmol) in ethanol (4 ml) was treated with N-(cyclopropylmethyl)propan-1-amine (45.3 mg; 0.4 mmol). The mixture was heated to 160° C. in a microwave for 1 hour and then filtered and the solvent removed in vacuo. The residue was purified by column chromatography (silica) eluting with petroleum ether containing increasing amounts of EtOAc to give tert-butyl 3-(4-(6-((cyclopropylmethyl)(propyl)amino)pyrimidine-4-carboxamido)-3-methylphenylsulfonamido)propanoate which was used directly without any further purification. The residue was redissolved in DCM (4.5 ml) and treated with TFA (0.5 ml). After stirring at RT for 2 hours the solvent was removed in vacuo to give the title compound as an off-white solid.
