Reaction Steps

A mixture of 3-chloro-2-nitro-N-(tricyclo[3.3.1.13,7]dec-1-ylmethyl)-benzamide (2.80 g, Example 1a) and piperazine-1-carboxylic acid, tert-butyl ester (7.47 g) in dry dimethyl sulfoxide (10 ml) was heated at 120° C. under a nitrogen atmosphere for 24 h. The cooled reaction mixture was diluted with water and extracted thrice with ethyl acetate. The combined extracts were washed with water, dried over sodium sulfate, filtered, and the filtrate concentrated under reduced pressure to give a solid. Purification by chromatography over silica gel, eluting with iso-hexane/ethyl acetate (2:1) gave the subtitle compound as a solid (3.8 g).
