Procedure

[4-(1,4-dioxa-8-azaspiro[4.5]dec-8-ylsulfonyl)phenyl]methanamine 7b (3.00 g, 10.1 mmol) was dissolved in DCM (20 ml), pyridine (976 μl, 12.1 mmol), 4-chlorobenzoyl chloride (1.41 ml, 11.1 mmol) and dimethylaminopyridine (catalytic amount) were added and the mixture was stirred at room temp overnight. Excess benzoylchloride was scavenged with aminomethyl-PS (2.0 g, 2.2 mmol) by shaking for 2 h. The resin was filtered off and washed with DCM (20 ml). The combined filtrates were washed with saturated aqueous citric acid (20 ml), dried over magnesium sulphate and evaporated to dryness to yield 2.7 g (59%) sulfonamide 4-chloro-N-[4-(1,4-dioxa-8-azaspiro[4.5]dec-8-ylsulfonyl)benzyl]benzamide 7c in >90% purity (LC-MS).
