Reaction Steps

N-(tert-Butoxycarbonyl)-N-[4-(dimethylazaniumylidene)-1,4-dihydropyridin-1-ylsulfonyl]azanide (38 mg, 0.12 mmol, prepared according to the Org. Lett., 2001, 3 (14), pp 2241-2243) was added to a solution of compound 111 (100 mg, 0.12 mmol, Example 26) and DIEA (54 μL, 0.38 mmol) in DCM (1 mL). The resulting mixture was stirred at rt for 3 h and concentrated. The residue obtained was purified by flash column chromatography on silica gel (0:1-1:0 EtAOc/hexane) to obtain compound 28a. Mass Spectrum (LCMS, ESI pos.) Calcd. for C30H37N7O6S: 624.2 (M+H). Found 624.2.
