Procedure
The title compound was prepared according to the procedure described in Example 4, Step 2, starting from 2-chloro-3-[2-(2-methoxyphenoxy)-1-methylethoxy]pyrazine* (150 mg, 0.51 mmol) and N-ethylpiperazine (222 mg, 1.94 mmol) with the exception that a final extraction step between EtOAc and 5% aqueous NaOH was carried out. This gave 127 mg (67%) of the title product. HRMS m/z calcd for C20H28N4O3(M)+372.2161, found 372.2174. Anal. (C20H28N4O3) C, H, N.
