Procedure

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) (0.295 g) in MeCN (1.1 mL) was added dropwise to a solution of (2-isopropylthiazol-4-yl)(1-oxa-4,9-diazaspiro[5.5]undecan-4-yl)methanone trifluoroacetate (example 22, step b) (0.150 g) and triethylamine (0.11 mL) in MeCN (1.1 mL) at RT under argon. The resulting mixture was stirred at 60° C. under argon for 34 h. After cooling to RT the solvent was removed in vacuo. The residue was taken up in DCM, washed with brine (×2), dried over sodium sulphate, filtered and evaporated in vacuo. The yellow solid was purified by silica gel chromatography eluting with 0-5% MeOH in DCM to give the subtitled compound as a green solid. Yield 0.135 g.
