SILATRANE synthesis

5synthesis methods
-

Yield: 89%

Reaction Conditions:

with sodium methylate in methanol;toluene

Steps:

2 Production of compound No. 4 of the invention (second process)
EXAMPLE 2 Production of compound No. 4 of the invention (second process) The same reactor as used in Example 1 was charged with 2.49 g (0.01 mole) of 1-(3-mercaptopropyl)silatrane and 100 ml of toluene, and the silatrane derivative was well dissolved. With stirring, 1.93 g (0.01 mole) of a methanol solution of sodium methylate (concentration 28%) was added dropwise. Then, 20 ml of a toluene solution of 5.54 g (0.01 mole) of trineophyltin chloride was added dropwise with stirring. The mixture was heated at 100° C. for 30 minutes to complete the reaction. The sodium chloride formed was removed by hot filtration. The filtrate was concentrated to give 7.7 g of a white solid. Recrystallization from ethanol gave 6.8 g (yield 89%) of 1-(3-trineophylstannylthiopropyl)silatrane as white crystals having a melting point of 104° to 106° C.
