Originator

Maiorad,Rotta,Italy,1982

Manufacturing Process

36.8 g (0.1 mol) of N-benzoyl-DL-tyrosil-di-n-propylamide are suspended in 350 cc of toluene; there are then added, under agitation, 5.4 g (0.1 mol) of sodium methylate and 50 cc (0.1 mol) of a titrated toluenic solution of 2-diethylamino-ethyl-chloride. The temperature is taken up to 105°C and the solution is left at this temperature, in agitation, for 12 hours. The toluenic solution is extracted with HCl 2 N; the aqueous acid phase is alkalized, cold, with sodium carbonate, and then reextracted with successive portions of ethyl acetate. The reunited organic phases are anhydrified upon anhydrous Na2SO4,filtered and dried off. The oily residue which is obtained crumbles after a few hours of rest. Amount obtained 39.2 g. Yield 84%. Melting point 65°C to 67°C (crystallizes with petroleum ether). The free base can be salified so as to render it hydrosoluble. For this purpose, for example, it is dissolved in acetone and precipitated as an oxalate by the addition of a solution of oxalic acid in ethanol. Recrystallizes with ethanol. Melting point (oxalate): 159°C to 162°C. Alternatively it can be dissolved in acetone and precipitated with an acetone solution of HCl. Recrystallizes with acetone-ethanol. Melting point (chlorhydrated): 181°C to 183°C.

Check Digit Verification of cas no

The CAS Registry Mumber 55837-29-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,5,8,3 and 7 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 55837-29:
(7*5)+(6*5)+(5*8)+(4*3)+(3*7)+(2*2)+(1*9)=151
151 % 10 = 1
So 55837-29-1 is a valid CAS Registry Number.
