Procedure
2,2,2-Trifluoroacetic acid (42.9 mL, 556.53 mmol) was added to tert-butyl 3-((tert-butyldiphenylsilyloxy)methyl)azetidine-1-carboxylate (Intermediate BG4) (9.87 g, 23.19 mmol) in anhydrous DCM (50 mL) at 0° C. then allowed to stirred at room temperature for 1 hour. The solution was concentrated and made basic using sodium hydroxide (250 mL, 2M) was added. the suspension was extracted with DCM and dried with Na2SO4 to afford the product (7.46 g, 99%)
