実験手順
To a stirred, ice-cold solution of 4-bromo-3-methyl-benzenesulfonyl chloride (11 g, 40.8 mmol) and N′N-diisopropylethylamine (8.5 ml, 49 mmol, 1.2 equiv.) in dichloromethane was added dropwise tert. butylamine (5.2 ml, 49 mmol, 1.2 equiv.). After two hours at room temp., the reaction mixture was diluted with water and extracted with dichloromethane. The organic extracts were concentrated under reduced pressure, the residue stirred with n-heptane and filtered to obtain 11.2 g of the desired compound as a yellow solid. MS (ES): m/e 304.2 (M−H)
