Procedure

The title compound was prepared according to the procedure of example 50, step 2, starting from 2-chloro-6-[5-(4-chlorophenyl)-2-methylfuran-3-ylmethoxy]pyrazine [3.14 g, 9.39 mmol; obtained according to the procedure of example 50, step 1, starting from 5-(4-chlorophenyl)-3-hydroxymethyl-2-methylfuran], piperazine (2.47 g, 28.6 mmol) and K2CO3 (1.36 g, 9.86 mmol) with the exception that the final filtration through alumina was omitted. The yield of the of the title compound was 2.11 g (58%) which was obtained as a beige colored solid. Purity 100% (HPLC). MS m/z 384 (M)+. HRMS m/z calcd for C20H21ClN4O2 (M)+ 384.1353, found 384.1357.
