Reaction Conditions

Reaction Steps

DIPEA (2 eq.) and HATU (1.2 eq.) were added to a solution of tetrahydrofuran and 2-(2-(2-chloro-N-cyclopropyl-6-methylphenylsulfonamido)ethoxy)acetic acid [acid K] (1 eq.) at 0° C. 4-(3-Fluorophenyl)-4-(2-(pyrrolidin-1-yl)ethoxy)piperidine [amine C] (1.2 eq.) was taken up in tetrahydrofuran (2 ml/mmol) and the solution was rendered basic with DIPEA (2 eq.) and added to the reaction mixture at 0° C. The reaction mixture was stirred at 25° C. for 16 h. The mixture was concentrated to dryness on a rotary evaporator, the residue was taken up in methylene chloride and the mixture was washed with water and sat. sodium chloride solution and dried over sodium sulfate. The organic phase was concentrated and the crude product was purified by means of column chromatography (5% methanol in methylene chloride). Yield: 60%. MS, Rt=3.6 min, m/z=622.4 [MH]+
