79% | In acetonitrile; at 20℃; for 48h; | A 25-mL one-neck flask was charged with a solution of <strong>[2848-01-3]3-(diphenylphosphino)propionic acid</strong>(0.15 g, 0.6 mmol) in MeCN (1 mL) and a solution of 2-acrylamido-2-methyl-1-propanesulfonic acid (0.13 g, 0.6 mmol) in MeCN (1 mL) with several drops of water. The reaction mixture was kept at room temperature for 48 h. After the completion of the reaction, the white precipitate that formed was collected by fi ltration, washed with diethyl ether, and dried using a rotary evaporator. Yield 0.22 g (79%), m.p. 218 C (from MeCN).
