2synthesis methods
-

Yield:-

Reaction Conditions:

with ammonia in methanol at 20; for 48 h;

Steps:

221.2 Step 2. Preparation of cyclopentanecarboximidamide

A solution of ethyl cyclopentanecarbimidate (16.0 g, 113.4 mmol) in ammonia (7.0 N in methanol, 125 mL) was stirred at rt for 48 h. After this time, nitrogen gas was passed through the mixture and the reaction was concentrated to afford the title compound (14.4 g, crude) as an off-white gum. MW = 112.17. ]H NMR (CD3OD, 500 MHz) δ 2.94- 2.80 (m, 1H), 2.16-1.99 (m, 2H), 1.91-1.79 (m, 2H), 1.78-1.64 (m, 4H); APCI MS m/z 113 [M + H]+.
