Participants

Reaction Steps

The same procedure described in the preparations a) and b) of Example 3.1. was used to react the 7-bromo-1-(2′,4′-dichlorophenyl)-4,5-dihydro-1H-thieno[2,3-g] indazol-3-carboxylic acid prepared in the Example 2.2 with 1-aminopiperidine. The purification by flash chromatography (oil ether/ethyl acetate 6/4) has given the compound N-piperidinyl-7-bromo-1-(2′,4′-dichlorophenyl)-4,5-dihydro-1H-thieno[2,3-g]indazol-3-carboxamide as white solid with a 42% yield. Rf=0.33 (oil ether/ethyl acetate 6/4); m.p.: 145° C.;
