Reaction Steps
Adapting procedures or variations thereof according to Lopez et al., Bioorg. & Med. Lett. 2003, 13(11), 1873-1878, a 500 mL round-bottomed flask equipped with a magnetic stirring bar was charged with 5.7 g (27.6 mmol) of 2,2-dimethyl-3-(phenylmethoxy)propanoic acid (26b), 20 mL of anhydrous dichloromethane (DCM), and 3 drops of N,N-dimethylformamide (DMF). Four-point-eight (4.8) mL (7.1 g, 55.2 mmol) of neat oxalyl chloride was slowly added to the solution. The reaction mixture was stirred at ca. 0° C. (ice-bath) for 5 hours. The solvents were removed under reduced pressure to provide the crude title compound (26c), which was used in the next step without further purification. 1H NMR (400 MHz, CDCl3): δ=1.34 (s, 6H), 3.54 (s, 2H), 4.56 (s, 2H), 7.29-7.37 (m, 5H) ppm. The analytical data was consistent with the proposed structure.
