Procedure

A solution of (1H-benzo[d]imidazol-2-yl)(4-(3-chloropyrazin-2-yloxy)phenyl)-methanone (23.00 g, 65.6 mmol) and morpholine (17.2 mL, 197 mmol) was heated to 90° C. in DMSO (165 mL). After complete consumption of the starting material, the hot solution was dripped into ice water which caused a yellow solid to precipitate. The solid was slurried in boiling EtOH (600 mL) and enough tetrahydrofuran was added to completely dissolve the solids. The solution was transferred to the freezer for crystallization. The solid was collected by filtration and air-dried to give (1H-benzo[d]imidazol-2-yl)(4-(3-morpholinopyrazin-2-yloxy)phenyl)methanone. MS (ESI, pos. ion) m/z: 402.1 (M+1). IC50 (uM) ++++.
