A solution of methyl-3-[3-({1-[2-(benzyloxy)phenyl]-1-methylethyl}amino)-2-oxopyrazin-1(2H)-yl]-4-chlorobenzoate (Example 330f, 2.23 g) dissolved in THF (30 mL) was treated with cyclopropylamine (2.261 mL) and 2.0M Isopropylmagnesium chloride (11.06 mL) under nitrogen. The resulting solution was stirred at 20° C. for 2 h. The reaction mixture was diluted with aqueous ammonium chloride (150 mL), and extracted with dichloromethane (250 mL). The organic was dried (MgSO4), filtered and evaporated to afford the subtitle compound (2.40 g).
