実験手順

To a stirred solution of 105 mg (0.22 mmol) of 1-(2,4,6-trichlorophenyl)-3-isopropyl-6-(4-aminobenzyl)pyrazolo[3,4-d]pyrimidin-4-one and 235 mg (1.09 mmol) of Boc-L-proline in 2 mL of DMF was added 0.35 mL (2.5 mmol) of triethylamine followed by 490 mg (1.11 mmol) of Bop. The solution was stirred overnight at ambient temperature then poured into EtOAc. This solution was washed sequentally with 0.5 M HCl then dilute aq. Na2CO3 then brine, dried (MgSO4), and concentrated under reduced pressure. The crude product was recrystallized from EtOAc-hexanes to afford 116 mg (80%) of (S)-1-(2,4,6-trichlorophenyl)-3-isopropyl-6-(4-(N-t-butoxycarbonylprolinamido)benzyl)pyrazolo[3,4-d]pyrimidin-4-one as a white solid, mp 225-226° C., Mass spec.: 657 M−H−).
