(9S)-2-(t-Butoxycarbonylamino)methyl-9-ethyl-9-hydroxy-1-pentyl-1H,12H-pyrano[3″,4″:6′,7′]indolizino[1′,2′:6,5]pyrido[4,3,2-de]quinazoline-10,13(9H,15H)-dione (33 mg, 0.056 mmol) was dissolved in trifluoroacetic acid (1 ml) and mixture was stirred for 1 hr. at room temperature. The solution was concentrated under reduced pressure and the resulting residue was purified by reverse-phase C-18 column chromatography to obtain pure product (27 mg, 80%).
