To a microwave tube was added ethyl 2-(3-aminooxetan-3-yl)acetate (CAN 1207175-54-9, 400 mg, 2.51 mmol) followed by toluene (8.0 ml) and 25% ammonium hydroxide (7.2 g, 8.0 ml, 51.4 mmol). The tube was sealed and the reaction mixture was stirred vigorously at room temperature for 6 days. The reaction mixture was concentrated in vacuo and azeotroped several times with 20 ml toluene. The crude solid was dried under high-vacuum at 40° C. to dryness to yield the title compound (290 mg, 89%) as a white solid. MS (ESI, m/z): 131.1 (M+H+).
