Reaction Steps

A flask containing 2,4-bis(4-methoxyphenyl)-1,3-dithia-2,4-diphosphetane-2,4-disulfide (387 mg, 0.957 mmol) was put under nitrogen atmosphere. 2-(tert-butyldiphenylsilyloxy)propanamide (622 mg, 1.899 mmol) dissolved in dry THF (10 ml) was added, temperature was raised to 60° C. and the mixture was allowed to react for 3 h. The solvent was evaporated and the product was extracted from DCM/water. The product was used in the next step without further purification. LC-MS: [M+1]=344.56.
