Procedure

To the solution of 3-[7-(azidomethyl)-1,1-dioxido-4H-thieno[2,3-e][1,2,4]thiadiazin-3-yl]-1-[(cyclopropylmethyl)amino]-4-hydroxyquinolin-2(1H)-one (357 mg, 0.62 mmol) in pyridine (4.6 mL) and concentrated ammonium hydroxide (3 mL) was added triphenylphosphine (397 mg, 1.51 mmol) at room temperature. The solution was stirred at room temperature overnight and concentrated under reduced pressure. The residue was diluted with 30% hexane/toluene and the solid was filtered to give 3-[7-(aminomethyl)-1,1-dioxido-4H -thieno[2,3-e][1,2,4]thiadiazin-3-yl]-1-[(cyclopropylmethyl)amino]-4-hydroxyquinolin-2(1H)-one (250 mg, 90%).
