Reaction Steps

To a solution of Example 59F (50 mg, 0.130 mmol) in dichloromethane (1 mL)/methanol (1 mL) was added triethylamine (0.036 mL, 0.260 mmol) followed by acetic acid (0.037 mL, 0.651 mmol) and (t-butyldimethylsilyloxy)acetaldehyde (0.050 mL, 0.260 mmol). After stirring for 5 minutes, MP-cyanoborohydride (2.49 mmol/g, 209 mg, 0.52 mmol) was added and the mixture was shaken for 16 hours at room temperature. The resin was filtered off, and washed with methanol/dichloromethane (2×3 mL). The crude mixture was concentrated and used in the next step without further purification. LCMS: 470.3 (M+H)+.
