Reaction Steps

To a solution of (R,S)-1-[2-(1-Hydroxy-propyl)-phenyl]-propan-1-ol (1.0 g, 5.15 mmol) in pyridine (1.22 g, 15.4 mmol) was added under exclusion of moisture phenyl phosphonic acid dichloride (1.0 g, 5.15 mmol). There is an exotherm and instant formation of pyridinium hydrochloride. The mixture was stirred over night. By 31P-NMR of the crude mixture there was complete conversion, and only one of two possible diastereoisomers present. After addition of HCl (5 ml of 4 N solution) the product was extracted with TBME (20 ml).
