文摘The crystal structure of the title compound （C34H47NTO9, Mr = 697.79） has been determined by single-crystal X-ray diffraction. The crystal belongs to monoclinic, space group P21 with a = 9.000（8）, b = 11.360（10）, c = 17.841（15.）/k, β = 97.083（14）°, V = 1810（3）A^3, Z = 2, F（000） = 744, D,.= 1.280 g/cm^3,/t = 0.094 mm^-1, the final R = 0.0721 and wR = 0.1942 for 2479 observed reflections with I 〉 2σ（I）. The two methyl groups attached to the cyclobutane ring are cis oriented. An intramolecular hydrogen bond （N（6）-H（6）…O（8）） introduces rigidity into the title molecule and the crystal structure is stabilized by intermolecular N-H…O hydrogen bonds.
