実験手順

Solid KOtBu (442 mg, 3.95 mmole) was added to a solution of tert-butyl 4-(7-bromo-2-chloroquinazolin-8-yloxy)piperidine-1-carboxylate (500 mg, 1.13 mmole) and 4-aminobenzenesulfonamide (777 mg, 4.62 mmole) in IPA (15 mL). The reaction was sealed and heated to 105° C. with stirring. After 2.5 hours, AcOH was added to the reaction to pH 4 and the reaction was evaporated to a solid. The crude product was dissolved in DMSO (15 mL) and purified by prep. HPLC to give 241 mg of product in 37% yield (417 mmole).
