実験手順

A mixture of Intermediate 29 (0.2 g, 0.997 mmol), 2-(3-methoxyphenyl)cyclopropanamine (FSSI, mixture of cis/trans, 0.163 g, 0.997 mmol), HATU (GenScript Corporation, 0.455 g, 1.196 mmol), hunig's base (Aldrich, 0.696 ml, 3.99 mmol) in DMF (0.997 ml) and DCM (0.997 ml) was stirred at room temperature overnight. Reaction mixture was diluted with DCM and washed with water and brine. The organic layer was loaded onto a Biotage samplet (25 g). Purification (0-100% EtOAc/hexane) produced 2-(3-chloropyrazin-2-yl)-N-(2-(3-methoxyphenyl)cyclopropyl)-2-methylpropanamide (0.183 g, 0.529 mmol, 53%). M+1: 346.0.
