Reaction Steps

To a solution of 3 (200 mg, 0.72 mmol) in dry DMF under an argon atmosphere was added 8 eq of CH3I (0.36 mL) followed by 2 eq of 95% NaH (37 mg). The reaction mixture was stirred overnight at room temperature. The reaction mix was added to 15 mL of H2O and extracted with 3×15 mL of Et2O. The combined organic layers were washed with 3×20 mL H2O followed by the usual work up. Purification of the crude product via silica gel column chromatography (7.5% EtOAc in hexane) afforded the methylated species 4 (181 mg, 86%) as a colorless oil: 1H NMR (CDCl3) δ 1.44 (9H, s), 1.46 (9H, s), 1.51 (3H, s), 2.94 (3H, s), 4.51-5.04 (2H, m). Anal. (C14H26FNO4) C, H, N.
