Reference of 480-91-1

General procedure: Phthalimidine (800 mg, 6.01 mmol) was dissolved in THF(40 mL). At ambient temperature triethylamine (670 mg,6.62 mmol) was added dropwise and the mixture was stirred for5 min, whereupon dichlorophenylphosphine (538 mg, 3.01 mmol)was added and the mixture was stirred for one day. Thereafter thewhite precipitate was filtered and washed with THF (3 mL). Thecombined filtrate and washings were evaporated to dryness (condensationof volatiles into a cold trap under reduced pressure), theresidue was dissolved in THF (10 mL) and the solution was filteredthrough Celite. After vapor diffusion of n-pentane into the filtrate(for one week), white crystalline product suitable for single-crystalX-ray diffraction was obtained. The supernatant was removed bydecantation, the white solid was washed with n-pentane (3 mL)and dried in vacuo to yield 480 mg (1.29 mmol, 43%) of 1b.
