실험 절차

A solution of (R)-2-(4-((tert-butoxycarbonyl(2-hydroxy-2-(4-hydroxy-2-oxo-2,3-dihydrobenzo[d]thiazol-7-yl)ethyl)amino)methyl)phenoxy)ethyl methanesulfonate (example 108, step c) (0.426 g) in MeCN (2 mL) was added dropwise to a solution of (5-methylthiophen-2-yl)(1-oxa-4,9-diazaspiro[5.5]undecan-4-yl)methanone trifluoroacetate (example 9, step b) (0.154 g) and triethylamine (0.15 mL) in MeCN (5 mL) at RT under argon. The resulting mixture was stirred at 60° C. under argon for 16 h, and then at 80° C. for an additional 3 h. After cooling to RT the solvent was removed in vacuo. The residue was taken up in DCM, washed with brine and water (×2), dried over sodium sulphate, filtered and evaporated in vacuo. The brown solid was purified by silica gel chromatography eluting with 0-10% MeOH in DCM to give the subtitled compound as a yellow solid. Yield 0.246 g.
