実験手順
A mixture of t-butyl 4-(2-chloroquinazolin-4-yl)piperazine-1-carboxylate (30 g) synthesized in the same manner as in Example 1, (S)-1-benzyl-3-aminopyrrolidine (15 g), triethylamine (8.7 g), and isopropyl alcohol (43 mL) was heated to reflux for 40 h. The reaction mixture was concentrated under reduced pressure, then water was added to the residue, and the mixture was extracted with chloroform. The organic layer was dried with anhydrous magnesium sulfate, concentrated, and then purified by silica gel column chromatography (NH silica gel, hexane/ethyl acetate=4:1) to obtain t-butyl 4-(2-((S)-1-benzylpyrrolidin-3-ylamino)quinazolin-4-yl)piperazine-1-carboxylate (26 g).
