Procedure
2-(2,2-Dimethyl-5-oxo-[1,3]-dioxolan-4-ylidene)-N-(4-fluorobenzyl)-N-isobutoxy-acetamide was treated with methanol as described in the preparation of Compound 44-D and gave the title ester as white crystals (48% yield); mp 55–56° C. 1HNMR 400 MHz (CDCl3) δ (ppm): mixture of rotamers: 0.99 (6H, d, J=7.1 Hz, CH3), 1.96 (1H, m, CH), 3.65 (2H, d, J=6.0 Hz, OCH2), 3.91 (3H, s, OCH3), 4.81 (2H, s, NCH2), 6.49 (1H, s, CH), 7.05 (2H, m, aromatics), 7.33 (2H, m, aromatics), 13.4 (1H, broad s, OH). HRMS (ES+) calculated for C16H21FNO5, [M+H]+: 326.140376. found: 326.139560.
