Procedure

To a solution of 2-(3-nitro-phenyl)-ethanol (1 eq) in dichloromethane at 0° C. was added pyridine (4 eq) and methanesulfonyl chloride (2 eq). After stirring at 0° C. for one hour, then room temperature overnight, the mixture was diluted with dichloromethane and washed once with water, once with 1 N HCl, dried with anhydrous sodium sulfate, filtered and concentrated. The product was clean enough to be taken on to the next step without purification. MH+=246.0.
