Ed in vacuo to give a black cake. The cake was dissolved in dichloromethane (four mL), and also the flask was flushed with argon. A remedy of diethylamine (0.055 g, 0.750 mmol) in anhydrous DCM (2 mL) was added by a syringe. The resulting green answer was stirred overnight then concentrated in vacuo. Trityls 11 and 15 had been isolated by column chromatography on silica gel (TFA in DCM, 1:1000 v/v after which DCM saturated with aqueous ammonia) to provide pure 11 (0.062 g, 47 ) and 15 (0.057, 42 ) as a black powder (bluish-green in DCM option).

Alternative Preparation for Trityl 15 A answer of three (0.132 g, 0.146 mmol) in anhydrous dichloromethane (3 mL) and CF3SO3H (0.044 g, 0.293 mmol) was stirred at area temp. for 2 h below argon. The resulting deep green solution was added by syringe slowly over 30 min to a stirred solution of diethylamine (0.320 g, four.38 mmol) in DCM (1 mL). The homogeneous option was stirred overnight at area temp., then water (six mL) was added. The mixture was stirred and left within the air for 30 min. The organic phase was separated, as well as the water phase was extracted with CH2Cl2 (three 3 mL). The combined organic extracts had been filtered via a quick cotton plug and concentrated in vacuo. Column chromatography on silica gel (DCM/hexane, 1:1 v/v then DCM) afforded trityl 15 (0.111 g, 82 ) because the only solution.NIH-PA Author Manuscript NIH-PA Author Manuscript NIH-PA Author ManuscriptSupplementary MaterialRefer to Web version on PubMed Central for supplementary material.AcknowledgmentsThe authors thank Drs.
