1335316-40-9 Usage

Uses

(5S)-N-(Methoxycarbonyl)-L-valyl-5-methyl-L-proline is an antiviral agent and Velpatasvir (V116000) intermediate. Velpatasvir is a NS5A inhibitor in patients with hepatitis C (HCV) infection.

Synthesis

To an ice-cold stirred solution of ethyl (2S,5S)-1 -[(2S)-2- (methoxycarbonylamino)-3-methyl-butanoyl]-5-methyl-pyrrolidine-2- carboxylate (5.6 g, 17.8 mmol) in ethanol (18 ml) is added a solution of lithium hydroxide monohydrate (17.8 mL of 1.7 M, 30.3 mmol). The reaction mixture is stirred for 5 hours at rt. The reaction mixture is concentrated, diluted with water, washed with ether. The aqueous solution is acidified with aq. 1 N HCl, extracted with CH2CI2. The combined extracts are washed with brine, dried (Na2S04), concentrated to afford (2S,5S)-1 -[(2S)-2-(methoxycarbonylamino)-3- methyl-butanoyl]-5-methyl-pyrrolidine-2-carboxylic acid (5g, 94%) as a white solid.

Check Digit Verification of cas no

The CAS Registry Mumber 1335316-40-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,3,5,3,1 and 6 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1335316-40:
(9*1)+(8*3)+(7*3)+(6*5)+(5*3)+(4*1)+(3*6)+(2*4)+(1*0)=129
129 % 10 = 9
So 1335316-40-9 is a valid CAS Registry Number.
