4-(4,4,5,5-tetramethyl-[1,3,2]dioxaborolan-2-yl)-3,6-dihydro-2H-pyridine-1-carboxylic acid tert-butyl ester (Tetrahedron Letters, 2000, 44, pp 3705-3708, 500 mg, 1.617 mmol) was added 2 mL DCM and 2 mL TFA. The mixture was stirred at room temperature for 3 hours. The solvents were evaporated in vacuo to afford the title compound (323 mg, 96% yield). The product was not further purified for next step. MS (ES+): m/z 210.19 (100) [MH+]; HPLC: tR=0.55 min (UPLC, Analytical).
