반응 단계

To a solution of phosgene in toluene (20% w/w, 2.2 mL, 4.2 mmol), cooled in an ice bath, was added dropwise a solution of 60 (321 mg, 1.9 mmol) in 2 mL of toluene. The mixture was stirred in the same bath, which was left to come to room temperature on its own. After 18 h, the mixture was concentrated in vacuo to give 61, which was used in the next step without further purification. 1H NMR (400 MHz, CDCl3) δ 2.30 (s, 3H), 5.28 (s, 2H), 7.13 (d, J=8.6 Hz, 2H), 7.42 (d, J=8.7 Hz, 2H).
