Yield: 84.6%

Reaction Conditions:

with triethylamine in dichloromethane at 20; for 17 h;

Steps:

15 synthesis of compound SM-6c
The substrate (2 g, 6.1 mmol)Was dissolved in anhydrous dichloromethane (24 mL),Triethylamine (0.85 mL) was slowly added,The reaction solution becomes viscous;Then Boc2O (1.4 g, 6.1 mmol) was added,The reaction solution was stirred at room temperature for 17 hours,LTC shows complete reaction.The reaction solution was transferred to a separatory funnel,Followed by water (4 mL),Saturated sodium bicarbonate solution (4 mL),And saturated brine (4 mL)The organic phase was dried over anhydrous sodium sulfate,filter,The filtrate was concentrated to give 1.84 g of a yellow oil,The column chromatography gave 1.32 g (84.6%) of pure product as a colorless oil.
