solution to give N-(p-tolythiomethyl) derivatives [corresponding to the general formula (4; R2= H)], usually in high yields. When the latter compounds are heated, under reflux, with an excess of sodiumborohydride in ethanol or 1,2-dimethoxyethane solution, the corresponding methylamino-compounds [general formula (5; R2= H)] are obtained. By a similar two-step procedure in which aqueous formaldehyde is

Multigram synthesis of (chlorosulfonyl)benzenesulfonyl fluorides is described. Selective modification of these building blocks at the sulfonyl chloride function under parallelsynthesis conditions is achieved. It is shown that the reaction scope includes the use of (hetero)aromatic and electron-poor aliphatic amines (e.g., amino nitriles). Utility of the method is demonstrated by preparation of the
