Procedure
4-(4-but-2-ynyloxy-benzenesulfonyl)-1-(4-methoxy-benzyl)-piperidine-4-carboxylic acid ethyl ester was prepared according to the general method as outlined in Example 1. Starting from (4-but-2-ynyloxy-benzenesulfonyl)-acetic acid ethyl ester (2 g, 6.73 mmol) and bis-(2-chloro-ethyl)-(4-methoxy-benzyl)-amine (2.61 g, 8.75 mmol) and following the procedure as outlined in Example 1 (Step 6) 2.5 g of the product was isolated. Yield 2.5 g (77%); yellow oil; MS: 486 (M+H)+.
