Reaction Steps

to anhydrous EtOH (30 μl) was added P2S5 (7.30 mg, 0.02 mmol) and the mixture stirred in a sealed vial for 1 h at RT. To the reaction mixture was added a solution of Compound 14 (51 mg, 0.0033 mmol) in anhydrous EtOH. (30 μl). The mixture was heated in a sealed vial at 120° C. for 3 h and then cooled to RT, whereupon water was added and the mixture extracted with DCM. The aqueous layer was concentrated to dryness and the residue purified by column chromatography silica gel (elution gradient ethyl acetate to 17% methanol in ethyl acetate) to afford Compound 21: ESI-MS m/z 340 ([M+H]+).
