実験手順

Trifluoroacetic acid (1.25 mL) was added to a solution of (R)-tert-butyl 4-(2-(4-(benzo[d]thiazole-2-carbonyl)-1-oxa-4,9-diazaspiro[5.5]undecan-9-yl)ethoxy)benzyl(2-hydroxy-2-(4-hydroxy-2-oxo-2,3-dihydrobenzo[d]thiazol-7-yl)ethyl)carbamate (example 106, step c) (0.33 g) in DCM (4 mL) and the resulting mixture stirred for 10 minutes. Toluene (20 mL) was added and the mixture was evaporated in vacuo. The residue was azeotroped with toluene (3×20 mL). Purification was by preparative HPLC (Phenomenex Gemini®, Gradient: 5-40% acetonitrile in 0.1% aqueous formic acid). The fractions containing product were combined and freeze-dried to give the titled compound as a white solid. Yield 0.096 g.
