It is stirred for 10 mins more at 0° C. and then a solution of 518 mg (4.007 mmol) of N,N-diisopropylethylamine in 4 ml dichloromethane is added dropwise. After two hours' stirring at room temperature the reaction mixture is evaporated and the crude product (1300 mg, 99% of theory) further reacted without purification.
