Procedure

Tosic acid (1384 mg) was added to a solution of N-cyclohexyl-N-(2,2-dimethoxyethyl)-3-(3-((4-(2-methylthiazole-4-carbonyl)-1-oxa-4,9-diazaspiro[5.5]undecan-9-yl)methyl)phenethoxy)propanamide (Example 277, step c) (683 mg) in DCM (10 mL) and the resulting mixture stirred at ambient temperature for 4 h. Sodium bicarbonate solution (saturated, 10 mL) was cautiously added and the mixture stirred until bubbling ceased (10 min). The reaction was diluted with DCM (50 mL) and the aqeuous separated. The organic was washed with saturated sodium bicarbonate solution (2×20 mL), brine (2 0 mL), dried over sodium sulphate, filtered and evaporated to afford the subtitled compound.
