Reaction Steps

The compound of Step 1 (600 mg, 1.68 mmol), piperazine (174 mg, 2.02 mmol), Pd2(dba)3 (77 mg, 0.084 mmol), BINAP (157 mg, 0.252 mmol), and sodium tert-butoxide (226 mg, 2.35 mmol) were mixed together and degassed followed by the addition of toluene (20 mL). The mixture was heated to 100° C. for about 16 hours. The mixture was cooled to r.t, and then diluted with ether (50 mL), filtered through celite and concentrated. The residue was subjected to SCX purification, and the resultant oil was chromatographed on silica gel (MeOH (NH3 2M)/DCM) to give the final compound (311. mg, 51%) as a yellow foam. MS found 362.3, M+1
