Reaction Steps

The above reaction and purification were repeated in a similar fashion using #104 (2.60 g, <3.35 mmol, 1 eq.), #103 (750 mg, 3.35 mmol, 1 eq.), dichloromethane (10 mL, 0.3 M) and diisopropylethylamine (1.35 mL, 7.73 mmol, 2.3 eq.) to give #105 (2.4 g, 92%) as a tan foam. Fractions containing impure product (1.7 g) were combined with the previous impure fractions and purified as described above to afford additional #105 (1.30 g, quantitative yield for both reactions over two steps). LC-MS: m/z 779.3 [M+H+], 802.3 [M+Na+], retention time=1.05 minutes.
