Reaction Steps
To a solution of cis-3-hydroxy-cyclobutanecarbonitrile (500 mg, 5.15 mmol in DMF (3 mL) at room temperature was added imidazole (876 mg, 12.9 mmol) followed by TBDMS-Cl (854 mg, 5.66 mmol). The reaction mixture was stirred at room temperature overnight then quenched with water and extracted with EtOAc (2×). The combined organics were washed with water (3×), dried over MgSO4 and concentrated. The residue was purified by silica gel chromatography with 0% to 10% EtOAc/hexanes to afford 890 mg (82%) of cis-3-(tert-butyldimethylsilanyloxy)-cyclobutanecarbonitrile as a colorless oil. 1H NMR (CDCl3, 400 MHz): δ (ppm) 4.10-4.19 (m, 1H), 2.57-2.67 (m, 2H), 2.43-2.54 (m, 1H), 2.22-2.34 (m, 2H), 0.84 (s, 9H), 0.00 (s, 6H).
