To a solution of sodium methoxide (1.2 equivalent, 4.0 ml of 1M solution in methanol) in tert-butyl methyl ether (12 ml) was added N-nitroso-N-benzyl-p-toluenesulphonamide (966 mg, 3.34 mmol) in small portions at room temperature. After the addition was finished the reaction mixture was refluxed for 15-30 minutes. The reaction mixture was cooled and washed with water (3×12 ml). The etheral solution of phenyldiazomethane was dried over sodium sulphate for 30 minutes.
