Reaction Steps

Crude chloride of Step 1 was dissolved in 1,4-dioxane and Cs2CO3 (2 eq.) was added. The reaction mixture was stirred at 100° C. overnight, then cooled down to room temperature, taken up in EtOAc washed with brine, dried over Na2SO4. The solvent was removed under reduced pressure and the resulting brown oil was purified by RP HPLC (C18, 5 μM, H2O/MeCN with 1% of TFA as eluant). Lyophilization of appropriate fractions gave title compound as a white solid.
