Procedure

The reaction was carried out similarly as described in the preparation of compound 138, using compound 435 (0.24 mmol) and 1-methyl-piperazine (0.5 mL). The crude product was purified by continuous gradient flash chromatography using MeOH/DCM 0:100 to 15:85 as the eluent to afford the title compound as yellow foam.
