Procedure:
To N,N-diisopropylamine (2.54 mL, 18 mmol) in anhydrous THF (15 mL), under N2 at −78° C. was added n-BuLi dropwise (2.5M in n-hexanes, 7.2 mL, 18 mmol) and the reaction mixture maintained at this temperature for 30 minutes. A solution of N,N-diethyl-2,3-dimethyl-benzamide (1.23 g, 6 mmol) in anhydrous THF (15 mL) was added dropwise to give a deep red solution. After 20 minutes at −78° C., 4-bromobenzonitrile (1.09 g, 6 mmol) in anhydrous THF (15 mL) was added dropwise and the reaction mixture allowed to stir at this temperature for 2.5 h. The reaction mixture was quenched by adding dropwise onto ice, upon which a pale yellow solid precipitated out. The solid was triturated with iso-hexane/EtOAc (2:1), filtered and dried in vacuo to afford 3-(4-bromo-phenyl)-5-methyl-2H-isoquinolin-1-one as a pale yellow solid (1.1 g, 58%).

Procedure:
To a stirred solution of 4-hydroxymethylbenzoic acid (3.33 g, 21.9 mmol) in DMF (100 mL), was added potassium carbonate (5.67 g, 41.04 mmol) followed by 2-(3-bromopropyl)-1,3-dioxolane (3.0 g, 19.9 mmol). The resulting mixture was heated at 80° C. for 16 hours. The reaction mixture was diluted with ethyl acetate and washed sequentially with water and twice with brine. The organic phase was dried with anhydrous magnesium sulfate, and filtered, and the filtrate evaporated at reduced pressure. The crude material was purified by silica gel chromatography eluting with 100% iso-hexane to 100% ethyl acetate in iso-hexane to afford the title compound as a colourless oil (2.55 g, 48%).

Procedure:
Ethyl-N-[bis(ethylthio)phosphinothioylmethyl]-N-(benzyloxycarbonyl)glycine (4.0 g.) was dissolved in 10 ml. of 35% hydrobromic acid in acetic acid and stirred for one hour. Ether was then added to precipitate the desired material as the hydrobromide salt. The residue was washed three additional times with ether. The residue was then dissolved in benzene and treated with excess propylene oxide. The propylene oxide-benzene solution was then concentrated in vacuo to yield a yellow oil (1.5 g.) which was chromatographed on fluorosil with diethyl ether as an eluant to yield ethyl-N-[bis(ethylthio)phosphinothioylmethyl]glycine as an oil, ND25 =1.582.
