m-Tolyl isocyanate → HCID 15670978, compound

Participants

Reaction Steps

Following a procedure analogous to that described in Example 106, but using 1.0 g of 2-amino-N-[2-(8-aza-1,4-dioxaspiro[4,5]decan-8-yl)-2-oxoethyl]-N-phenylacetamide and 0.4 g of 3-methylphenyl isocyanate as the starting material, 0.6 g of N-[2-(8-aza-1,4-dioxaspiro[4,5]decan-8-yl)-2-oxoethyl]-2-[3-(3-methylphenyl)ureido]-N-phenylacetamide melting at 130° C is obtained after recrystallization from a cyclohexane/ethyl acetate mixture (50/50 by volume).
