The crystal structure of the title compound (C34H47N7O9, 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) , β = 97.083(14)°, V = 1810(3) 3, Z = 2, F(000) = 744, Dc = 1.280 g/cm3, μ = 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.

The crystal belongs to monoclinic space group P21 with a = 9.000 (8), b = 11.360 = 17.841 (15) β, β = 97.083 (14) °, V = 1810 33, Z = 2, F 000 = 744, Dc = 1.280 g / cm 3, 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 (8)) introduces rigidity into the title molecule and the crystal structure is stabilized by intermolecular NH ... O hydrogen bonds.
