Versuchsvorschrift
This compound was obtained in a crude 100% yield according to the procedure described for the synthesis of 1-methoxymethylcyclopropylsulfonylamine tert-butyl-carbamate except that 1.10 equivalents of n-propyl isocyanate was used as the electrophile. The compound was taken directly into the next reaction without purification: 1H NMR (CDCl3) δ 0.10 (m, 2H), 0.51 (m, 2H), 0.67 (m, 1H), 1.10 (m, 2H), 1.49 (s, 9H), 1.62 (m, 2H), 1.87 (d, J=7.0 Hz, 2H).
