Participants

Reaction Steps

CH2N2 (1.04 g, 248.1 mmol) in ether (10 mL) was added to 4-[tert-butyl(dimethyl)silyl]oxybutanoic acid (5.41 g, 24.81 mmol) in a flask. The mixture was stirred overnight, concentrated to give the title compound (5.44 g, 95%). 1H NMR (400 MHz, CDCl3): δ 0.03 (6H, s), 0.88 (9H, s), 1.81-184 (2H, m), 2.39 (2H, t, J=7.2 Hz), 3.63 (2H, d, J=6.4 Hz), 3.66 (3H, s). [M+H] Calc'd for C11H24O3Si, 233. Found, 233.
