Procedure
Isopropylmagnesium chloride (5.86 mL of a 2M solution in THF) was added over 20 min to a solution of cyclopropylamine (2.066 mL) and 3-[3-[[1-(5-fluoro-2-hydroxyphenyl)cyclopropyl]amino]-2-oxo-1(2H)-pyrazinyl]-4-methyl-benzoic acid methyl ester (Example 278c, 1.2 g) in THF (200 mL) at room temperature under nitrogen. The reaction mixture was stirred for 1 h. Water and 2M HCl were cautiously added and the aqueous layer extracted with dichloromethane (3×200 mL), dried (MgSO4) and the solvent removed to give the subtitle compound (1.22 g)
