The reaction mixture was added to saturated aqueous ammonium chloride solution and extracted twice with diethyl ether, and the combined organic phases were dried over magnesium sulfate and concentrated. 2.47 g (94% of theory) of the title compound were obtained and were reacted without further purification.
