With phosphoric acid; sodium nitrite; In water; at 10 - 25℃; | Example 2. Preparation of N-nitroso-dimethylurethane in toluene o MeOA N - N Me N-Nitroso-dimethyl urethane H3PO4 50% in water (9.2 g, 48 mmol) is added to dimethylcarbamate (4.9 g, 55 mmol) at 10 - 20 C under stirring. To the colorless 2-phase mixture is added NaN02 30% in water (20.1 g, 67 mmol) at 10 - 15 C over 1 - 1.5 h. Nitrous gases are formed at the end of the addition and the orange solution is stirred for 17 h at 25 C. Nitrogen is bubbled through the reaction mixture to expel remaining nitrous gases. Stirring is stopped and a sample is taken from the orange organic layer for analytical analysis which shows a conversion of 88 - 92% according to GCMS and NMR. The reaction mixture is extracted twice with toluene (15 ml, 10 ml) to give 30 ml of a clear light orange solution which is used as such in the cyclopropanation step. Analytical data of the organic layer before toluene addition: 1H-NMR (CDC13, 400 MHz): 4.1 (s, 3 H), 3.2 (s, 3 H) ppm. 13C-NMR (CDC13, 400 MHz): 154.2 (s), 54.9 (q), 28.0 (q) ppm. GC/MS: 118 (20%, M+), 87 (10%), 59 (100%), 56 (20%), 43 (77%), 42 (26%), 30 (74%), 28 (21%). |
