Procedure

To 152 (0.2007 g, 0.5 mmol) dissolved in THF (10 mL) was added a solution of N-methyl-4(methylamino)piperidine (0.07 mL, 0.5 mmol) in THF (1 mL) followed by the addition of DIEA (1.0 mL, 0.55 mmol) in acetonitrile (1 mL). The reaction mixture was allowed to stir at reflux overnight under nitrogen. The reaction mixture was extracted 3 times with dichloromethane; the combined organic layers were washed with brine and dried over potassium carbonate. The sample was concentrated on a rotary evaporator and the resulting oil was dried overnight under vacuum. Column chromatography (90:9:1 dichloromethane:methanol:conc. ammonium hydroxide) yielded a light yellow solid 154 (65 mg, 27%), mp 100° C.; TLC (silica gel, 90:9:1 CH2Cl2:CH3OH, conc. NH4OH), Rf 0.36; MS (ESI): m/z 475 (M+H, 23.2), 378 (11.6), 258 (68.9), 239 (52.2), 238 (100).
