Procedure
The product of Example 125 (3.92 g, 0.01 tool) was reduced with sodium dithionite (6.96 g, 0.04 mol) according to the procedure of Example 126. A yield of 2.2 g (65% ) of the title compound was obtained as an orange-yellow amorphous powder, m.p. 55°-60° C. UV max (methanol) 358 nm; IR (CHCl3) 3325 (NH), 1682 (CO), 1645 (CO) cm-1. Anal. calc. for C18H23N3O2. 3/4H2O: C,66.07; H,7.49; N,12.85. Found: C,66.05; H,7.56; N,12.84. The structure of the product was further confirmed by PMR to be: ##STR1505##
