The reaction mixture was then stirred at 120° C. for 30 min under microwave heating. After cooling, the mixture was diluted with water (40 mL) and the resulting precipitate collected by filtration, washed with water and dried in vacuo to give the desired product (750 mg, crude, 97% yield) which was used in next step without further purification. LCMS (m/z): 338.1 [M+H]+
