实验步骤: A solution of (3-Amino-oxetan-3-yl)-acetic acid ethyl ester (CAN 1207175-54-9, 0.3 g, 1.88 mmol) in methanamine 41% aqueous solution (1.86 g, 2.09 ml, 24.5 mmol) was stirred overnight at 60° C. The reaction was evaporated down to dryness and to yield the title compound (278 mg, 102%) as a crude solid which was used without any purification. MS (ESI, m/z): 145.2 (M+H+). The reaction was evaporated down to dryness
