Compound 14 was prepared from Compound 7 using a procedure analogous to that described previously for Compound 20. Recrystallization of the crude product from ethyl acetate gave a 59% yield of a white solid, m.p. 125.5°-127° C. Analysis: Calculated for C16H26N4OS2 : C, 54.21; H, 7.39; N, 15.80. Found: C, 53.51; H, 7.21; N, 15.72.
