実験手順

A solution of compound 29 (300 mg, 0.54 mmol) in 50 ml TFA/CH2Cl2 (1:1) was stirred for 2 hr at ambient temperature, then concentrated under vacuum. Two cycles of toluene addition and removal of volatiles gave 250 mg of 30 as a white solid (92%) which was used in the next step without purification. ESI ES+=502.3 (M+1).
