A 10 mL flask was charged with methyl 2-((S)-(3-chlorophenyl)((R)-4-((2S,3R)-3-hydroxy-4-(N-methyl-N-(2-(trimethylsilyl)ethoxycarbonyl)amino)-1-(tetrahydro-2H-pyran-4-yl)butan-2-ylcarbamoyl)morpholin-2-yl)methoxy)ethylcarbamate (30 mg, 0.043 mmol) dissolved in MeCN (4 mL) and Et4NF (14 mg, 0.094 mmol) was added. The mixture was stirred for 0.5 h under reflux. After stirring, it was monitored by HPLC until the reaction ended. The solution was concentrated in vacuo and purified by HPLC to give the target compound (2.97 mg, 12%). 1H NMR (MeOD) 1.27-1.30 (m, 2H), 1.32-1.40 (m, 2H), 1.51-1.62 (m, 2H), 1.65-1.80 (m, 2H), 2.70 (s, 3H), 1.75-1.90 (m, 2H), 1.90-3.10 (m, 4H), 3.65 (s, 3H), 3.80-3.95 (m, 5H), 4.05-4.20 (m, 1H), 4.30 (m, 1H), 7.25-7.40 (m, 4H).
